Question

what is the answer of the question plz Tel me

Answer 1

Hi
2-a
3- angle 2 = angle 4 = x (say)
angle 1+ angle 2 + angle 3 +angle 4 = 360°
222° + 2x = 360°
2x = 360-222
x = 138/2
x = 69
so,angle 2 = 69°

4- If AB = AC
(angle opposite to equal angle are equal)
angle B = angle C = x
angle A + angle B + angle C = 180°
70° + x + x = 180°
2x = 180° - 70°
x = 110°/2
x = 55°

5- 1) angle Q = angle F
2) PE = ED
3) angle P = angle E
4) QR = FD

6- angle x = 75°
angle y = 180-75
= 105°
