1. Two parallel lines AB and CD are cut by a 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.
the rational number on the number line​

Answer 1

Answer:

Since sum of cointeriors is 180°.

Therefore,

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

Answer 2

Answer:

x = 15 ...............
