Answer:

x=10, y=20

Step-by-step explanation:

180-20-=160

160-90=7x

7x=70

x=10

5x+2y=90

5(10)+2y=90

50+2y=90

2y=40

y=20

Hope this helps! :)

Answer:

x=10     y= 20

Step-by-step explanation:

to find x use the 20* and the 90* from the top to get 110

then use the straight  line to subtract 110     180-110=70  

then do 70 / 7 =10

to find y solve for 5x first to get 50 add 70* from the vertical angle to get 120

then use the vertical angle from 20* to get 140

then use the straight line to subtract  140          180-140=40

then do 40/2 = 20
