Question

12. In the given figure, AB II CD. Find the value of x. В B D Q E G P to 85° (н 115° F R А C​

Answer 1

Answer:

x=20°

Step-by-step explanation:

PEF=DGQ

DGQ=85°

DGQ+QGH=180°

85°+QGH=180°

QGH=180-85=95°

CHQ+QHG=180°

115°+QHG=180°

QHG=180-115=65°

IN ∆HGQ,

QGH+QHG+GQH=180°

95°+65°+x=180°

160°+x=180°

x=180-160

x=20°
