Question

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

Answer 1

Answer:

x=85

y=55

Step-by-step explanation:

Sum of angles in a triangle is 180

x,y are unknown

let the third angle be z which is 40

x-y=30 (given)

x+y+z= 180

x+y=180-z

x+y=180-40

x+y=140

from equation 2 and 3

x+y=140

x-y=30

by solving above equation

we get

2x=170

x=85

putting the value of x in equation 3 we will get

85+y=140

y=140-85

y=55
