Supplementary angles mean that two angles equal to 180°.
Let us assume the 2 angles are angle A and angle B.
Angle A is 4 times bigger than Angle B, the supplement.
Let Angle B be represented by x.
Angle A is 4x ; Angle B is x.
4x + x = 180°
5x = 180°
x = 180°/5
x = 36° This is the measure of angle B.
4x = 4(36°) = 144° This is the measure of angle A.
4x + x = 180°
144° + 36° = 180°
180° = 180°
Answer:
x = P/8
Step-by-step explanation:
The perimeter of the blueprint is given by the equation :
P = 8x
We need to solve the above equation for x.
Dividing both sides of the equation by 8.

Hence, the value of x is P/8
Answer:
x = -10
Step-by-step explanation:
10 + 7x = - 60
- 10 = - 10
7x = -70
x = -10
2.3 is the same as 2 1/3 is the same as 7/3
3 2/3 is the same as 11/3
11/3+7/3=18/3
18/3=6
Answer:6
