Answer 2

Answer:

q21-)

given

x-y=30

a triangle having angles- x,y,40

to find-

value of x and y

Step-by-step explanation:

x-y=30

x=30+y

x+y+40=180.(ASP of triangle)

putting value of x

30+y+y+40=180

2y+70=180

2y=180-70

2y=110

y=110/2

y=55

so, x=y+30

putting value of y

x=55+30

x=95

therefore

x=95,y=55
