Answer:
30 degrees
Step-by-step explanation:
This is an isosceles triangle having 2 equal sides and 2 equal base angles.
since the measurement of all the internal angles of the triangle is 180 degrees and we know that each base angle is 75 degrees
solving for x:
75 + 75 + x = 180 degrees
150 + x = 180
x = 180 - 150
x = 30 degrees
