Question

please tell answer briefly​

Answer 1

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°

Answer 2

Step-by-step explanation:

Let QTR be a triangle

Therefore 180=x+40+90

x=180-40-90

X=50
