Question

4. If (X/2x) = X then X=
(where X + 0)*
a. 2x2
O b.1/3x2
O
01/2
O d.-1/2x2​

Answer 1

Answer:

I don't know 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°
