Question

1- in each case given below find the value of x ​

Answer 1

• draw line n parallel to l and m

4x-10°= a & 3x+3°=b (corresponding angles)

4x-10°+3x+3°=91°

7x-7°=91°

7x=91°+7°

7x=98°

x=98/7°

x=14°

• draw line n parallel to l and m

a=54°(corresponding angles) & b+110°=180°( co-interior angles)

b=180°-110°

b=70°

a+b+x=360°( angles around a point)

54°+70°+x=360°

124°+x=360°

x=360°-124°

x=236°
