Question

Help guys

D, E, F, G and H are points on the circumference of the circle G1=x+20 and H=2x+10. DE||FG
a) determine the size of DEG in terms of x
b) calculate the size of DHG​

Answer 1

Explanation:

A. DEG =x+20 (alt angles DellFg)

B. DHG =110 (opp angles of cyclic quad)

X+20+2x+10=180(remember to solve for x)
