∠A = 45 °
∠B = 110 °
∠C = 25 °
Explanation:
We know that sum of all angles of triangle is 180°.
x + x + 65 ° + 25 ° = 180 °
combine like terms
2 x + 90 ° = 180 °
Subtract 90 ° from each side
2 x + 90 ° - 90 ° = 180 ° - 90 °
2x = 90 °
Divide 90 ° by 2.
x = 90 ° / 2
x = 45 °
Therefore,
∠A= x = 45 °
∠B = x + 65 ° = 45 ° + 65 ° = 110 °
∠C = 25 °
