Question

two angles of a triangle are equal and the third angle is 30 degree more than the other two angles.find the angle​

Answer 1

Answer:

Let the two equal angles be x°. Then, the third angke will (x+30)°. ... So, two equal angles of the triangle are 50° and the third angle is 80°.

Answer 2

Answer:

first angle is x second angle is y third angle is 30 +x+y

x+y+30+x+y=180

2x+2y+30=180

2x+2y=180-30=150

x+y=150/2

x+y=75

x and y are same so 75 degree
