In the diagram below, if arc AB measures 62 ° and arc DC measures 102 °, find the measure of < APD.
alex41 [277]

The measure of angle < APD = 98°. That is option D

<h3>Calculation of the missing angle</h3>

Angle APB = 62°

Angle DPC = 102°

But length AD = BC

Therefore, angle APD = BPC

Also, the angle at a point = 360°

The sum of the angles given = 102 + 62 = 164°

The remaining angle = 360 - 164 = 196°

Therefore angle APD = 196/2 = 98°
