X+y=180 degrees (being angles a straight line) Q. If x-y=40 degree then find the value of x and y

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

x+y+40=180

x+y=140

difference between  x and y is 30.

x−y=30 (2)

2x=170

⇒x=85

Substitute this value n equation (2), we get

85−y=30

⇒y=85−30

⇒y=55

angles of a triangle are x=85, y=55 and 40.

Step-by-step explanation:

366

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
