My teacher is making us do this but we haven’t learned it test someone

Hello from MrBillDoesMath!

35 degrees

Discussion:

The angle shown is a right angle. That is, it contains 90 degrees. So we need to solve

90 = 7x + 11x               => as 7x + 11x = 18x

90 = 18x                      => divide both sides by 18

x= 90/18 = 5

The measure of the smaller angle is 7x = 7(5) = 35

Thank you,

MrB

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
