WebIf you know the measures of two angles in a triangle, you can use the Triangle Sum Theorem to find the measure of the third angle. Find the missing angle measure. Write the Triangle Sum Theorem for this triangle. m∠D + m∠E + m∠F = 180° STEP 2 Substitute the given angle measures. 55° + m∠E + 100° = 180° Solve the equation for m∠E. WebOA = OX since both of these are equal to the radius of the circle. The triangle AOX is therefore isosceles and so ∠OXA = a. Similarly, ∠OXB = b. Since the angles in a triangle add up to 180, we know that ∠XOA = 180 - 2a. Similarly, ∠BOX = 180 - 2b. Since the angles around a point add up to 360, we have that ∠AOB = 360 - ∠XOA - ∠BOX.
