*Complete Question:
Given the diagram below, where and mDE = 105^ and mGE = 125^ Find m<DEG
Answer:
m<DEG = 65°
Step-by-step explanation:
Angle DEG is an inscribed angle that intercepts the DG. Based on the theorem of inscribed angles, angle DEG = ½ of the measure of arc DG.
To find the measure of angle DEG, find the measure of arc DG first.
Measure of arc DG = 360° - (105° + 125°) => a full circle measures 369°
Arc DG = 360° - 230 = 130°.
m<DEG = ½ of 130° = ½*130° = 65°
