Question

4. AXYZ is an equilateral triangle ZYVW = 90° and XZW is a straight line. Find Za?
(a) 60°
(b) 30°
(c) 45°
(d) 15°​

Answer 1

Answer:

a= 30°

Step-by-step explanation:

angle YVW + WYX = 180 (LINEAR PAIR)

THEREFORE ANGLE WYX = 90°

BY APPLYING ASP IN TRAINGLE WVX

ANGLE V + ANGLE X + ANGLE W = 180

90 + 60(EQUILATERAL TRAINGLE) + a = 180

a = 30°

Answer 2

Answer:

(B) 30°

Step-by-step explanation:

in∆XVW XVW= 90°

VXW= 60°. ( Angle of equilateral triangle)

XWV=a

V+X+W= 180

90+60+a =180

150+a=180

a=180-150

a=30
