M∠r = 120 and m∠s = 110. find m∠t. the diagram is not to scale.

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.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
