Question

The angle of a triangle are x,y and 40° the differences between two angles a and y is 30° find x and y.​

Answer 1

Answer:

X=85, y=55

Step-by-step explanation:

Given that, x, y and 40° are the angles of a triangle.

x + y + 40° = 180° [since, the sum of all the angles of a triangle is 180°]

Hence, the required values of x and y are 85° and 55°, respectively.

Answer 2

Step-by-step explanation:

x+y+40=180

x+y=180-40

x+y=140

x=140-y -----(1)

x-y=30

140-y-y=30

140-2y=30

-2y=30-140

-2y=-110

2y=110

y=55

Put y=55 in eq (1)

x=140-55

x=85
