Answer:
∠1 = 51° ∠2 = 39°
Step-by-step explanation:
ok since the picture is a right angle put it equal to 90
like this:
3x + x + 22 =90
4x + 22 = 90
4x = 68
x = 17
now we plug it in:
3(17)= 51°
(17) + 22 = 39°
*a straight line is equal to 180, a right angle is 90
does that make sense?

Answer:
x = - 1 ; y =0
Step-by-step explanation:
−10y+9x= −9 --------------> EQU 1
10y+5x= −5 --------------> EQU 2
____________________
0 + 14x = -14 { add EQU 1 and EQU 2 }
x = -14/14
x = -1
Substitute the value of x in EQU 1;
-10y + 9 *(-1) = -9
-10y - 9 = -9
-10y = -9 +9 = 0
y = 0
