Answer:
Step-by-step explanation:
x+165 = 180
x = 180 - 165
x = 15
Answer:
measure of exterior angle at C = 160°
Step-by-step explanation:
An exterior angle of a triangle equals the sum of the two remote interior angles
A and B are the remote interior angles. So,
m∠A + m∠B = measure of exterior angle at C
5x - 10 + 12x = 16x
17x - 10 = 16x
x = 10
measure of exterior angle at C = 16x = 16(10) = 160°
Answer:
Area of parallelogram is equal to 
Step-by-step explanation:
It is given length pf parallelogram which is equal to base of parallelogram is b=15 cm
Height of parallelogram h = 7.5 cm
We have to find the area of the parallelogram.
Area of parallelogram is equal to multiplication of base and height.
Therefore area of parallelogram is,
, here b is base and h is height.
So 
Therefore area of parallelogram is equal to 
15 + 6(x + 1)
Factor a 3 out of the expression.
3(5 + 2(x + 1))
Distribute the 2.
3(5 + 2x + 2)
Combine like terms.
3(7 + 2x)
3(7 + 2x) is your answer.
