Question

Two adjacent angles of a Parallelogram are (3x -4) and (3x + 10). Find the angles of the Parallelograms. [ pls write the steps ] [ pls fast need it fast ]

Answer 1

Answer:

(3x -4) + (3x + 10) = 180°

3x - 4 + 3x + 10 = 180°

6x + 6 = 180°

6x = 180 - 6

6x = 174

x = $\frac{174}{6}$

x = 29

∠1st = 3 × 29 - 4 = 83°

∠2nd = 3 × 29 + 10 = 97°
