Answer:
C. 35°
Step-by-step explanation:
Look at the picture.
We have the supplementary angles. Supplementary angles add up to 180°.
Therefore the measure of first is 55° and the second angle is 90°.
We know: The sum of the measures of the angles in the triangle is equal 180°.
Therefore
p° = 180° - (55° + 90°) = 180° - 145° = 35°
