Answer 1

Answer:

5x +35=45

5x =45-35

x=10\5

x=2

Answer 2

$\huge \underline \bold{Solution}$

In the given figure, we have to find the value of x

As l || m

So,x + 45° = 180 (linear)

=> x = 180°-45°=135°

=>x =135°= 5x + 35 (alternate interior angle)

=>5x=100°

=>x=100/5

=>x=20

Hence, the value of x is 20°
