Question

Q. Find the lettered angles in fig (ii).
Find x and y‌‌ ? Solve the Solution.​

Answer 1

Step-by-step explanation:

In traingle ADC,

40°+90°+y=180°(angle sum property of traingles)

130°+y=180°

y=180-130

y=50°

In traingle ABD,

Angle ADB =90°(as angle ADC and angle ADB forms a linear pair )

60°+90°+x=180°

150°+x=180°

x=180-150°

x=30°

Answer 2

Step-by-step explanation:

X+60°=180°

X=180°-60°

X=120°anwer

Y+40°=180°

Y=180°-40°

Y=140°answer
