The measure of angle a is 35 degrees, b is 55 degrees and c is 110 degrees.
We have to determinewhat are the measures of angles a, b and c?
According to the questionAngles a and 35 are vertical angles and vertical angles are equal.
<a = 35
We have a triangle with a, b, and a right angle.
Triangles have angles that add to 180.
<a + <b + 90 = 180
35 + <b + 90 =180
125 + < b = 180
<b = 180-125
<b = 55
Angle c and 70 form a straight line and straight lines are 180 degrees.
<c+70 = 180
<c = 180-70
<c = 110
Hence, the measure of angle a is 35 degrees, b is 55 degrees and c is 110 degrees.

Check the picture below.
∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.
∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.
∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.
