Question

The measures of the angles of a triangle are shown in the figure below. Solve for x. 30° 49° (8x-11)°

Answer 1

X = 101 degrees

Explanation:

The sum of all the angles of a triangle is 180 degrees.

(8x - 11) + 49 + 30 = 180

8x - 11 + 79 = 180

8x + 68 = 180

8x = 180 -68

8x/8 = 112/8

x = 14

(8x - 11) = ?

(8(14) - 11) = 101

so ... X = 101 degrees

101 + 30 +49 = 180 degrees
