Question

6. Two angles of a triangle are equal and the third angle is greater than each of those
angles by 30°. Determine all the angles of the triangle.
​

Answer 1

Answer:

Then, the third angke will (x+30)°. We know that sum of three angles of a triangle is 180°. On solving the equation, we will get x as 50°. So, two equal angles of the triangle are 50° and the third angle is 80°.

Answer 2

Answer:

50°,50°,80°

Step-by-step explanation:

let equal angles be x each

then, other angle will be x+30°

By angle sum property,

x+x+x+30=180°

3x=150

x=50°

now 50+30=80°
