Question

pls solve step by step​

Answer 1

Answer: 55°

Step-by-step explanation:

As l//m

So,

ANGLE1=ANGLE5

(because they are corresponding angles)

ANGLE1=2x-15°

ANGLE5=x+40°

So,

2x-15°=x+40°

2x-x=40+15

x=55°

Answer 2

Answer:

Step-by-step explanation:

given    <1=2x-15        <5=x+40

    <1=<5    corresponding angles

therefore

   2x-15=x+40

   2x-x=40-15

      x=25
