Answer:
y = 90°
x = 50°
Step-by-step explanation:
We know that:
Sum of all angles of the triangle = 180°
Thus, in ∆QTR
Angle TQR + Angle QTR + Angle TRQ = 180°
40° + 90° + x = 180°
x = 180° - (40 + 90)°
x = 180° - 130° = 50°

Step-by-step explanation:
Let QTR be a triangle
Therefore 180=x+40+90
x=180-40-90
X=50
