Question

two Parallel Lines ab and CD are cut by the transversal EF if the interior angles of the same side of EF be (4x+27) and (7x-12), Find the measure of each of these angles. ​

Answer 1

Answer:

Since sum of cointeriors is 180°.

Therefore,

$4x + 27 + 7x - 12 = 180 \\ 11x + 15 = 180 \\ 11x = 165 \\ x = 15$

So angles are

4x + 27 = 4×15 + 27 = 60 + 27 = 87°

7x - 12 = 7 × 15 - 12 = 105 - 12 = 93°

Answer 2

Answer:

$x = 15$

is the correct................
