Question

plz ans it in full method​

Answer 1

Answer:

x = 22

∠3 = ∠1  = 129°

Step-by-step explanation:

Because corresponding angles are equal

3x - 15 = 2x + 7

x = 22

-----------------------

∠1 = 180 - (3x - 15) ...................... (linear pair)

∠1 = 180 - 51 = 129°

-----------------------

Because alternate exterior angels are equal

∠3 = ∠1  = 129°

Answer 2

Step-by-step explanation:

(3x-15) = (2x+7).. { corresponding angle are equal.}

3x-2x=7+15

x =22

Answer 3

Step-by-step explanation:

(3x-15) = (2x+7).. { corresponding angle are equal.}

3x-2x=7+15

x =22
