Question

a)Find the measure of angle C , A and B if measure angle D = 80 degree. State the reasons for your answers

pls i need it now :(

Answer 1

Answer:

angle C = angle D = 80°......................... ( vertically opposite angles)

angle C + angle B = 180°........................ ( straight line angle)

angle B = 180° - 80° = 100°

angle A = angle B = 100°........................ ( vertically opposite angles)

Hope this helps to you...!!

Answer 2

Answer:

$\huge\mathfrak\pink{☆Answer☆}$

Step-by-step explanation:

Angle D=80°

So D+B=180° (Linear pair).

80°+B=180°

B=180-80

B=100°.

Now Angle B=Angle A (Vertically opposite angles).

80°=A

So A=80°.

Similarly D=C (Vertically opposite angles).

100°=C

So C=100°.

So from here=>

1. Angle A=100°
2. Angle B=100°
3. Angle C=80°

These are the required answers.

HOPE IT HELPS.
