Question

Q3. In the figure below, find the values of x and y. A y 70 B C D​

Answer 1

Answer:

x = 55° y = 125°

Step-by-step explanation:

∠CBA + ∠BAC + ∠ACB =180° (angle sum property)

70 + x + x = 180

2 x = 180 - 70

x = 110 / 2

x = 55°

∠CBA + ∠CAB = ∠ACD (ext. ∠ = sum of int. opp. ∠)

70 + 55 = y

y = 125°
