Answer:
Step-by-step explanation:
Note that the base angle of an isosceles triangle is equal hence;
3x+2 = 5x-30
3x - 5x = -30-2
-2x = -32
x = -32/-2
x = 16
Hence one of the base angle = 3(16)+2 = 50degrees
The sum of angle in the triangle is 180, hence
50+50+y = 180
100 + y = 180
y = 80 degrees
Hence the third angle is 80 degrees
