Question

m∠R = 120 and m∠S = 110. Find m∠T.
The diagram is not to scale.

Answer 1

The sum of the interior angles of a quadrilateral always add up to 360 degrees. Because we know this, we can find the missing angle. We know two angles currently, angle R and angle S.

Because angle U is equal to angle S, we have three angles:

120, 110, and 110.

120 + 110 + 110 = 340

Because there is only one remaining angle, we can find the length like so:

360 - 340 = 20.

The final angle, T, is equal to 20 degrees.

Answer 2

Based on the information given, the value of angle T will be 20°.

It should be noted that the sum of the interior angles of a quadrilateral always add up to 360 degrees.

Therefore, based on the angles given. This will be:

120° + 110° + 110° + T = 360°

340° + T = 360°

T = 360° - 340°

T = 20°
