The measure of the angles are :
25°129°x = 107° ; y = z = 73°167°52°Angle 1 = 109° ; Angle 2 = 71°To find x :
A right angle = 90°
65 + x = 90
x = 90° - 65°
x = 25°
(2) :
Vertically opposite angles are equal :
Sum of angles at a point = 360°
[(51 × 2) + (2x)] = 360°
106° + 2x = 360°
2x = 360° - 102°
2x = 258°
x = 254° ÷ 2
x = 129°
(3.)
Verticaly opposite angles are equal :
107° = x°
y° = z°
(2y + (2 × 107)) = 360°
2y + 214° = 360°
2y = 360° - 214°
2y = 146°
y = 146° ÷ 2
y = 73°
y = z = 73°
4.)
Measure of supplementary angles = 180°
Let the measure of it's supplement = x
x + 13° = 180°
x = 180° - 13°
x = 167°
5.)
Complementary angles add up to 90°
Let the measure of it's complement = x
x + 38° = 90°
x = 90° - 38°
x = 52°
6.)
Sum of linear pair of angles = 180°
(5x + 9) + (3x + 11) = 180°
5x + 3x + 9 + 11 = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20°
Angle 1 = 5(20) + 9 = 109°
Angle 2 = 3(20) + 11 = 71°

A baseball team won 16 games and lost 11. At this rate, how many games will it win in a 162-game schedule?
==========================================================
Explanation:
The team won 16 games and lost 11 so far. At this point in the season, they played 16+11 = 27 games total. Their win rate is 16/27.
Set this equal to x/162 which is the win rate for winning x games out of 162 played over the entire season.
Solve for x.
x/162 = 16/27
27x = 162*16 ... cross multiplication
27x = 2592
x = 2592/27
x = 96
The team would win 96 games if it kept the same winning rate going.
Notice that 16/27 = 0.5926 = 59.26% and how 96/162 = 0.5926 = 59.26% as well (both are approximate). This helps confirm we have the correct answer.
-------------------------
Here's another slightly longer way to solve. If you prefer the first method above, then ignore this section.
w = number of games won over the entire 162 game season
162-w = number of games lost over the entire season
w/(162-w) = win to loss ratio
16/11 = win to loss ratio after winning 16 games and losing 11
Setting those last two expressions equal to each other and solving for w gets us...
w/(162-w) = 16/11
11w = 16(162-w)
11w = 2592-16w
11w+16w = 2592
27w = 2592 ... this hopefully looks a bit familiar from before
w = 2592/27
w = 96 games won

Answer:
f(3) + f(-3) = 10
Step-by-step explanation:
f(3) = 5 - 2(3)
f(-3) = 5 - 2(-3)
f(3) + f(-3) = 5 - 2(3) + 5 - 2(-3)
f(3) + f(-3) = 5 - 6 + 5 +6
f(3) + f(-3) = -1 + 11
f(3) + f(-3) = 10

no. for it to be dilated it must be similar, thus the corresponding sides must be equal in ratio. however the bases 12 and 10. are not in equal ratios as the other sides which is half

What is a cube root? A fourth root? A fifth root? Explain.
Do all numbers have a cube root? A fourth root? A fifth root? Explain.
Answer:
In mathematics, a cube root of a number x is a number y such that y³ = x. All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x: {\displaystyle r^{n}=x, } where n is a positive integer, sometimes called the degree of the root. A root of degree 2 is called a square root and a root of degree 3, a cube root.

Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
Hello there!
We are given a function below:
[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]
To find f(-10), substitute n = -10.
[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]
Evaluate the f(-10)
[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]
Recall
Negative × Negative = PositiveTherefore,
[tex] \displaystyle \large{f( - 10) = 74}[/tex]
f(-10) = 74

A theater charges $4 for each matinee
ticket. If it sells 360 tickets for a matinee
performance, how much does it take in?
Answer:
1,440
Step-by-step explanation:
Because 360*4=1,440
Answer:
$1440
Step-by-step explanation:
What you're going to want to do is multiply 4 by 36 at first. This is going to get you to 144. If you really wanted to break it down, you can multiply 4 by 3, place a zero at the end, multiply 4 by 6, and add the totals. Next, since the question is 4x360 and not 36, we will need to place a zero at the end of the product. This will get you 1440. And so, the answer is $1440.

Is this relation a function?
Answer:
No
Step-by-step explanation:
The domain is the x-values and the range is the y-values. For a relation to be a function, each x-value has to be assigned to a DIFFERENT y-value, so you shouldn't have one x-value pointing to two different y-values. Since 14 is pointing to both 10 and 15, that means there are two coordinates with an x of 14 but with different y's, so the relation is not a function.
