Two angles of a triangle are equal and the third angle measures 70°...
Let the measure of each unknown angle be x°. We know that the sum of the angles of a triangle is 180°.
∴ x + x + 70 = 180°
⇒ 2x = (180° – 70°)
⇒ 2x = 110°
⇒ x = 55°
Hence each unknown angle is 55°.
∴ x + x + 70 = 180°
⇒ 2x = (180° – 70°)
⇒ 2x = 110°
⇒ x = 55°
Hence each unknown angle is 55°.

Two angles of a triangle are equal and the third angle measures 70°...
Let's assume that the two equal angles in the triangle each measure x degrees.
Since the sum of the angles in a triangle is 180 degrees, we can write an equation:
x + x + 70 = 180
Combining like terms:
2x + 70 = 180
Subtracting 70 from both sides:
2x = 110
Dividing both sides by 2:
x = 55
Therefore, each of the two equal angles in the triangle measures 55 degrees, and the third angle measures 70 degrees.
