Use the diagram below to answer the question. 6x + 15
10x - 5
14 What is the value of x?
Use the diagram below to answer the following questions.
1.
32 degrees
43 degrees
15 What is the measure of 21?
16) What is the measure of 23?

14- We know that by angle sum property sum of all angles = 180

so

6x+15+10x-5+90=180

16x+10=180

x= 180-10/16

x= 170/16=85/8

x= 10.625

15) angle 1 = 45 DERGE (:. by vertically opposite angle)

16) angle 2 = 32+ 45-180

angle 2= 103

Angle 3 = angle 2 + 45 degree - 180 degree. ( sum of of angle = 180)

Angle 3 = 103 degree+ 45 degree - 180 degre

angle 3 = 32 degree

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
