Question

Find the value of x for which a || b. Then find the measure of the labeled angles.

Answer 1

Answer:

The measure of the labeled angles is 135°

Step-by-step explanation:

we know that

if  a || b

then

$(3x-27)\°=(2x+27)\°$ -----> by alternate exterior angles

Solve for x

$3x-2x=27+27$

$x=54$

Find the measure of the labeled angles

$(3(54)-27)\°=135\°$
