Answer:
51
Step-by-step explanation:
All triangles =180 degrees
180-78 = 102
Since this triangle is an isosceles triangle, that means that 2 sides are the same length, and that 2 angles are the same.
102/2 (you divide by 2 bc the angles unknown are the same measurement) and that equals 51 degrees
This is a inscribed angle, so that the angle is 1/2 the measurement of the arc length.
You are trying to find q°
100/2 = 50
q° = 50°
hope this helps
