Question

NAME OF ANGLE 1 is ?
/_ ADC
/_ACD
/_ DAC

Answer 1

Step-by-step explanation:

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°

Answer 2

Answer:

180° is the answer of first one
