Question

Can u answer 1st question

Answer 1

Answer:55, 125 are the angles

Step-by-step explanation:

Since l is parallel to m

Therefore 3x+20+2x-15=180 (some property)

5x-5=180

x=35

Therefore the angles are 3x+20=3(35)+20=125,2x-15=2(35)-15=55

Answer 2

Step-by-step explanation:

3x + 20 + 2x - 15 = 180°

So, u must know value of x

• 3x + 20 + 2x - 15 = 180°

5x + 5 = 180°

5x = 175°

x = 175/5 = 35

And then, if u know value of x. U can subtitution in 3x + 20 and 2x - 15

• 3x + 20 = 3(35) + 20 = 125°

• 2x - 15 = 2(35) - 15 = 55
