Answer:
see explanation
Step-by-step explanation:
(1)
The sum of the 3 angles in a triangle = 180° , thus
a + b + c = 180
(2)
adjacent angles are supplementary, thus
b + d = 180
(3)
From (1) and (2)
b + d = a + b + c ( subtract b from both sides )
d = a + c

Aman decleared that he will give 20% discount on each items
in his shop. Sita bought a rice cooker from the shop at Rs.
3,500. If the shopkeeper made a profit of 5% on selling rice
cooker to Sita, find the cost price, marked price and discount
amount of the rice cooker.
Answers
Answer:
Let be cost price =Rs.100
Then mark price =Rs.120
∴ Selling price =90% of 120
=
100
120×90
=Rs.108
Profit = Selling price− Cost price
=Rs.(108−100)=Rs.8
Profit % =

The measures of the angles: m∠1 = 51°, m∠2 = 39°
Step-by-step explanation:
In this type of question, you should substitute the measures of the angle by the given values and solve the equation to find x, then find the measure of each angle.
∵ m∠1 + m∠2 = 90°
∵ m∠1 = 3x°
∵ m∠2 = (x + 22)°
→ Substitute m∠1 by 3x° and m∠2 by (x + 22)° in the equation above
∴ 3x° + (x + 22)° = 90°
→ Add the like terms in the right side
∴ (3x + x) + 22 = 90
∴ 4x + 22 = 90
→ Subtract 22 from both sides
∴ 4x + 22 - 22 = 90 - 22
∴ 4x = 68
→ Divide both sides by 4 to find the value of x
∴ [tex]\frac{4x}{4}=\frac{68}{4}[/tex]
∴ x = 17
→ Now substitute the value of x in each angle to find them
∵ m∠1 = 3x°
∴ m∠1 = 3(17) = 51°
∵ m∠2 = (x + 22)°
∴ m∠2 = (17 + 22) = 39°
The measures of the angles: m∠1 = 51°, m∠2 = 39°

A young sumo wrestler decided to go on a special diet to gain weight rapidly. WWW represents the wrestler's weight (in kilograms) after ttt months. W=80+5.4tW=80+5.4tW, equals, 80, plus, 5, point, 4, t What was the wrestler's weight before his special diet?
Answers
Answer:
80kg
Step-by-step explanation:
Given:
W = 80 + 5.4t
Where,
W = the wrestler's weight (in kilograms
t = number of months
What was the wrestler's weight before his special diet?
W = 80 + 5.4t
When t = 0 (that is before the weight gain)
W = 80 + 5.4t
= 80 + 5.4(0)
= 80kg
When t = 1 ( first month of the weight gain)
W = 80 + 5.4t
= 80 + 5.4(1)
= 80 + 5.4
= 85.4 kg
The wrestler's weight before his special diet is 80kg
ALTERNATIVELY
W = 80 + 5.4t
80 = the fixed weight
5.4 = weight gained per month
t = number of months
Therefore,
The fixed weight which is 80kg is the weight of the wrestler before the special diet.

FINDING ANGLE MEASURES Find the value of x. Then classify the triangle by its angles.
Answers
Answer:
i hope my answer is right for you
In the given triangle, the value of x is 60°.
What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.Equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene are the seven different kinds of triangles that can be found in nature.
So, the value of 'x':
We easily know that te given triangle is an equilateral triangle.Where all 3 angles are equal.The Sum of triangles is 180°.Now,
60 + 60 + x = 180120 + x = 180x = 180 - 120x = 60°
Therefore, in the given triangle, the value of x is 60°.
