Answer:
<a = 35
<b = 55
<c = 110
Explanation:
Angle 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
