Question

E
7. In the figure given alongside, find:
(1) angle ACD
(11) angle ADC
(111) angle DAE
50
40° 100
B​

Answer 1

Answer:

Angle ACB + Angle ACD = 180° (Linear Pair)

= 100 + ACD = 180

= Angle ACD = 80°

Angle ADC = 180 - (ACD + CAD)

[ASP of triangle]

= 180 - (80 + 50) = 180 - 130 = 50°

Angle BAC = 40° (Using ASP triangle)

Angle DAE = 180 - (DAC + BAC)

= 180 - (50 + 40) = 180 - 90 = 90°
