Question

The angles of a triangle are x, y and 40°. The difference between the two angles x and y is 30°. The values of x and y are ……………..*

1️⃣ 45°, 75°
2️⃣ 50°, 80°
3️⃣ 85°, 55°
4️⃣ 55°, 95​

Answer 1

Answer:

x = 85° , y=55°

Step-by-step explanation:

Given :- x, y, 40° are angles of a ∆

x-y = 30° ........ (1)

x+y+40 = 180° (by angle sum property of ∆) .......(2)

from 1

x= 30+y

put in 2

30+y+y+40 = 180

2y= 180-70

y =110/2

y =55°

.

. . x = 30 +55

= 85°
