Question

find the values of the unknowns 'x' and 'y' in the following diagrams​

Answer 1

x = 80° (V.O.A)

In ∆SRT,

50°+80°+y = 180° (angle sum property of a triangle)

130°+y = 180°

y = 180°-130°

y = 50°

Answer 2

Answer:

x= 80 (Vertical opposite angle)

then

x+y+50=180(being sum of triangle)

80+50+y=180

y=180-130

so y= 50
