Question

if AB // CD, Then find the value of . ∠P = ( 2x+ 40)° and ∠Q = ( x + 90 )°

Answer 1

Answer:

Step-by-step explanation:

angle P + angle Q=180 (corrsponding angle)

2x+40 + x+ 90= 180

3x+130 =180

3x= 50

x=50/3

please mark me brainlist

Answer 2

Answer:

∠P and ∠Q are 140°

Step-by-step explanation:

1. First find the value of x

2x+40=x+90

Minus x on both sides

x+40=90

Minus 40 and both sides

x=50

2. Now that we know what x is, we can substitute it into our equations

2x+40

(2×50)+40

100+40

= 140

∠P = 140°

x+90

50+90

= 140

∠Q = 140°

Hope this helps! :)
