the diagram shows triangle PQR. PSR is a straight line. Size of angle SQR 3:1. Work out the size of angle PSQ
Answers
The value of the size of angle PSQ of the given triangle is; 61°
What us the missing angle of the triangle?From the given triangle ΔPQR, we see that;
m∠QPS = 65°
m∠PRQ = 43°
Now, it is clear that Line PSR is a straight line divided in the ratio;
size of angle PQS : size of angle SQR = 3:1
m∠PQS : m∠SQR = 3:1
Thus, since sum of angles in a triangle is 180°, then we say that;
∠PQR = 180° - (∠QPS + ∠PRQ)
Plugging in the relevant values;
∠PQR = 180° - (65° + 43°)
∠PQR = 72°
Using the concept of angle addition postulate, we have that;
∠PQR = m∠PQS + m∠SQR
Since m∠PQS : m∠SQR = 3:1, then we have;
m∠PQS = 3 × m∠SQR
Thus;
∠PQR = (3 × m∠SQR) + m∠SQR
∠PQR = 4 × m∠SQR
4 × m∠SQR = ∠PQR
4 × m∠SQR = 72°
m∠SQR = 72°/4
m∠SQR = 18°
m∠PQS = 3 × m∠SQR
m∠PQS = 3 × 18°
m∠PQS = 54°
Finally;
∠PSQ = 180° - (65° + 54°)
∠PSQ = 61°

A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant (unlike permutations). Three fruits, such as an apple, an orange, and a pear, for instance, can be combined into three different pairs: an apple and a pear, an apple and an orange, or a pear and an orange. A k-combination of a set S is officially defined as a subset of S's k unique elements. So, if and only if each combination contains the same elements, two combinations are said to be identical. (It is not important how each set's members are arranged.) If there are n elements in the set, then C kn is the number of k-combinations.

The equation and the accompanying justification that describes a line that is parallel to EF is: C. Y = -1/3x + 5 1/3 the slopes are equal.
What is the Equation of Parallel Lines?If two lines are said to be parallel to each other, their equations that is expressed as y = mx + b, will have the same slope value of m. Y = mx + b is the slope-intercept form of any equation that represents a line.
Given that the equation y = -1/3x + 4 represents the line EF, its slope is -1/3. This means the slope of any line that is parallel to y = -1/3x + 4 will be the same as -1/3.

monica has a goal to complete a triathlon. the race consists of a 0.93-mile swim, a 24.8-mile bike ride, and a 6.2-mile run. in training, monica can swim at an average pace of 2.1mph. she rides her bike at an average of 18.8mph and runs at 5.1mph. estimate how long it will take her to complete the triathlon.
Answers
3.31 it will take her to complete the triathlon.
To find this, we can apply the equation distance = rate x time.
We are aware of the length and pace of each triathlon leg. Let's name them, respectively, d and r. We must locate the time, which we shall designate as t.
d = r x t or
t = d/r
The distance is 0.93, or 93/100, and the rate is 1.2, or 12/10 when swimming. As a result of our formula, we have:
12/10 divided by 93/100 yields the same result as
93/100 * 10/12
time to swim = 93/120 = 31/40
We have a distance of 24.8 miles, or 248/10, and a speed of 18.8 miles, or 188/10, for biking. Using the same formula, we obtain:
248/10 divided by 188/10 or
248/10 * 10/188 = 248/188 = 62/47 = time to bike
Finally, for the run, the distance is 6.2 = 62/10 and the rate is 5.1 or 51/10. Plugging this into the formula gives:
62/10 divided by 51/10 or
62/10 * 10/51 = 62/51 = time to run
= 31/40 + 62/47 + 62/51

Answers
If you have two options, A and B, exclusive means only one option is required (A or B) while inclusive means both options are available (A and B).
To calculate the answer to this question, we need to consider what the words “exclusive” and “inclusive” mean. Exclusive means that one option is required and the other is not, while inclusive means that both options are available. In the case of the question a, the answer is exclusive because you must take either chemistry or physics to graduate. In the case of question b, the answer is inclusive because you can have either a complimentary coffee or tea.
To illustrate the difference between exclusive and inclusive with a formula, we can use the following:
Exclusive: A + B = A
Inclusive: A + B = A + B
This formula demonstrates that if you have two options, A and B, exclusive means only one option is required (A or B) while inclusive means both options are available (A and B).

Answers
The sum of the numbers written on the faces of the cube is 333.
What is vertex?A vertex, also known as a point, is a fundamental part of a shape or an object. It is the point at which two or more lines, edges, or faces meet. Vertex can also refer to the corner of a polygon, where multiple lines meet. In 3D geometry, a vertex is a point where three or more edges meet. In a 3D object, each vertex is considered to be a corner of the object. Vertices are a crucial part of the structure and design of shapes, and can be used to define a shape's size, shape and dimension.
The sum of the numbers written on the faces of the cube is equal to the sum of the products of the numbers assigned to the vertices of the cube divided by three. Since the sum of the numbers assigned to all the vertices is equal to 1001, the sum of the numbers written on the faces of the cube is equal to 1001/3, which is equal to 333.

Step-by-step explanation:
You want a graph of ∆ABC, with A(4, 7), B(0, 0), and C(8, 1). You want to identify the congruent sides, construct an angle bisector, and comment on how it divides the opposite side.
GraphThe graph of the points, and the construction of the angle bisector are shown in the attachment.
a. Congruent sidesSince you have your compass available for construction, you can use set it to the measure of one side and compare that to the other two sides. It does not take long to identify AB ≅ BC. (A compass setting shows they are the same length.)
b. Angle bisectorAs you know, an angle bisector is constructed by first identifying two points on the sides of the angle that are the same distance from the vertex of the angle. Then two intersecting arcs are drawn with the same radius using those points as their centers. The vertex and the intersection of the arcs defines the ray that is the angle bisector. This is shown in the attachment.
c. AD and CDYou can count grid squares (or use the compass) to determine that AD and CD are the same length: D is the midpoint of AC.
This reinforces your knowledge that the angle bisector of the a.pex angle of an isosceles triangle is also an altitude and a median.
