Answer 2

Answer:

x = 55

y = 35

z = 90

Step-by-step explanation:

First angle = x

second angle = y

third angle = z

Here it is given that , x+y = z. (1)

x - y = 20. (2)

and we all know that sum of angles of a triangle is 180

so , x + y + z = 180. (3)

Now we have three unknowns and three equations ,so solve these three equations to find out angles

from third x + y = 180 - z

equate this and eq 1

so z = 180 - z

z = 90

now x + y =90

and x - y = 20

add these two , 2x = 110

x = 55

and similarly , y = 35

final angles , x = 55

y = 35

z = 90
