Ineed now ? the question is to find the value of the variables and the measure of each angle in the diagram

here we go

Step-by-step explanation:

13x+(4x+10)=180

Simply brackets

13x+4x+10=180

17x+10=180

-10

17x=180-10

17x=170

170/17=10

X=10

2(y+25)+2y−30=180

2y+50+2y−30=180

add like terms

4y+20=180

4y=160

160/4=40

Y=40

13x=130

(4x+10)=50

2(y+25)=130

(2y-30)=50

e) none of the above because the measure of angle cba is 101°

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
