Question

PQ and rs are parallel. for what value of X ab cd be Parallel state proper axiom or theorem . ​

Answer 1

Answer:

X=35

Step-by-step explanation:

3x-15°=90°

3x=90°+15°

3x=105°

x=105÷3

x=35

Answer 2

Answer:

x = 39°

Step-by-step explanation:

Since, PQ || RS

PEF = HFE (Alternate Angles)

Thus, angle HFE = 2x....

Also, CHF = GHF

( Vertically Opposite Angles)

So, GHF = 3x - 15

Now, If AB and CD r parallel,

GHF + HFE = 180

So, 5x - 15 = 180

or x = 195/5

hence, x = 39°......
