Question

In the given figures,find the values of x and y.​

Answer 1

For Figure 1:

$130 = 70 +x\\x= 60\\\\y=180-130\\y=50$

For Figure 2:

$y+50+85 = 180\\y=45\\\\\\x+40+(180-85) = 180\\x=85-40\\x=45$

Answer 2

Step-by-step explanation:

I) 130°+y=180°

y=180-130

y=50°

x+y+70=180°

x+50+70=180

x+120=180

x=180-120

x=60°

ii) 50+85+y=180°

135+y= 180

y=180-135

y=45°

50+y+40+x=180°

50+45+40+x=180

x+135=180

x=180-135

x=45°
