Answer:
∠A = 45°
∠B = 110°
∠C = 25°
Explanation:
We know that
the sum of the interior angles in a triangle is 180°.
Accordingly,
x + 65 + x + 25 = 180
Combine like terms.
2x + 90 = 180
Subtract 90 from both sides.
2x = 180 - 90
2x = 90
Divide both sides by 2.
x = 45°
Now let us find the exact value of the angles.
∠ A = x = 45°
∠ B = x + 65 = 45 + 65 = 110°
∠C = 25°
