Explanation:

For question no. 3

Since we are aware that measure of the sum of all the three interior angles of a triangle is 180°.

$135 \degree + 25\degree +( 2x + 2)\degree = 180 \degree \\ \\ \therefore \: 2x\degree = 180 \degree - 152 \degree \\ \\ \therefore \: 2x\degree = 28 \degree \\ \\ \therefore \: x\degree = (28 \degree)/(2) \\ \\ \therefore \: x = 14$
