Find the values of x and y.

Answer 1

Answer:

Step-by-step explanation:

a) As sum of angles in a triangle= 180

therefore ,45 °+75°+y=180°

120°+y=180°

y=180°-120°

∴y=60°

b)using vertically opposite angle y=80°

therefore using sum of angles in a triangle =180°

∴x+x+y=180°

2x+80°=180°(as y= 80°)

2x=180°-80°

2x=100°

x=50°
