Answer 1

Answer:

❣️ hello mate ❣️

Step-by-step explanation:

vertical opposite angle of 90 is 90

x+x+90=180

x=45

x+y=180. linear pair

y=180-45=135

Answer 2

Bonjour!

Given:

Let's call ∠ A = 90°

And, let's label the angle opposite to ∠A = ∠B

Now,

∠B + ∠x + ∠x = 180 ( angle sum property)

∠B = 90° (opposite to ∠A)

Now,

∠B + ∠x + ∠x = 180°

90° + 2∠x = 180°

2∠x = 180 - 90

2∠x = 90°

∠x = 90/2

∠x = 45°

Now, ∠x + ∠y = 180° (straight-line)

45° + ∠y = 180°

∠y = 180° - 45°

∠y = 135°

Merci !
