Question

Can you help me pls i need it

Answer 1

1. x = 40°

2. 4x - 25 = 135°

3. x + 5 = 45°

Explanation:

1.

According to the figure and since m//n then

The two angles of measures (respectively) 4x - 25 and x + 5 are supplementary .

Then

4x - 25 + (x + 5) = 180°

Then

5x - 20 = 180

Then

5x = 200

Then

x = 200/5

Then

x = 40°

……………………

2.

x = 40

Then

4x - 25 = 4(40) - 25 = 160 - 25 = 135°

…………………………………………………………

3.

x = 40

Then

x + 5 = 40 + 5 = 45°
