The correct answer is 
°.
To solve for
, you can start by finding the measures of the triangle's interior angles. Knowing that a straight line measures 
°, you can subtract the given values from ° to find the measures of the respective supplementary interior angles. That would give you 
° 
and 
° 
.
Now, knowing that the measure of all the interior angles of a triangle is also°, you can add the two interior angles you know 
and subtract those from °. Doing so would give you the measure of the missing third angle, which is 
°.
Finally, because angle is the supplementary angle of the missing angle from the previous step, simply subtract that angle's measure from ° to find °, which is 
or °.
