Step-by-step explanation:

1) 2x + x = 3x

2) 3y - 2y = y

3) 18 + 1 = 19

4) 3x + y = 19

5) y + -1y = 0

6) Divide each side by '3'.

x = 6.333333333 + -0.3333333333y

7) x = 6.333333333 + -0.3333333333y

An exterior angle of an isosceles triangle has measure 150°. Find two possible sets of measures for the angles of the triangle.

nasty-shy [4]

<span>_Award brainliest if helped!
If the exterior angle of the bases is 150°, then the measure of the angle of each base is
30° and the measure of the vertex is 120°. If the exterior angle of the vertex is 150°, then the measure of the angle of each base is
75° and the measure of the vertex is 30°.</span>
