Answer:

70° is your measurement for ∠t.

Explanation:

Note that a straight line has an angle of 180°

It is given to us that ∠r and ∠t = 180°, and that m∠r = 110°

Plug in 110 for ∠r

110 + ∠t = 180

Isolate ∠t. Note the equal sign, what you do to one side, you do to the other. Subtract 110 from both sides

110 (-110) + ∠t = 180 (-110)

∠t = 180 - 110

∠t = 70

70° is your measurement for ∠t.
