1) Find x
The equation is:
4x=64

x=64/4=16

answer: x=16º

2)Find y:
The equation is:
(2y)+(3y+5)=180
5y=180-5
5y=175
y=175/5
y=35

Answer: y =35º

Find the measure of each angle...
3)∠a
2y+4x+a=180
2(35º)+4(16º)+a=180º
70º+64º+a=180º
a=180º-70º-64º=46º

Answer: ∠a=46º.

4)∠b
a+b=180º
46º+b=180º
b=180º-46º
b=134º

Answer: ∠b=134º

5)∠c
a+c=180º
46º+c=180º
c=180º-46º
c=134º

Answer: ∠c=134º

6)∠d
112º+d=180º
d=180º-112º
d=68º

Answer: ∠d=68º

7) ∠e
64º+d+e=180º
64º+68º+e=180º
e=180º-64º-68º
e=48º

Answer: ∠e=48º

8)∠f
e+f=180º
48º+f=180º
f=180º-48º
f=132º

Answer: ∠f=132º
