Question

Z

(5x+6)°
10
Find m/Y.
A. 41°
B. 82°
C. 98°
D. 102°
Y
(8x - 15)°
10
X

Answer 1

Since the triangle has two equal sides, it is an isosceles triangle, so:

5x + 6 = 8x - 15
21 = 3x
7 = x

5(7) + 6 = 41, so angle X and Z equal 41 each.

Interior angles of triangles equal 180°

41 + 41 + angle Y = 180

82 + angle Y = 180

Angle Y = 98

Have a good day ^^

Answer 2

41 + 41 + Y = 180^o

82 + Y = 180

180 - 82 = 98 degrees.
