(PA) Unit 7 Lesson 7 - Double Transformations

Multiple Choice

Which set of triangle side lengths for a right triangle? Just choose one of them. Can we get a 100% ?

• 29, 420, 421

• 21, 480, 481

Remember how to do this? What number does supplementary angles add up to? Add the expressions you see together and set it equal to 180. Solve that equation. You know how.

For your answer...type only a number.

x = ?

Fill in the Blanks

Followup. Now we know that x = 33. So, what is the measure of angle QRT?

$m\angle QRT$
