Question

2)
Find the values of x and y in the following figure.
80 70

Answer 1

Step-by-step explanation:

angle x+angle y=180°

80°+70°+y=180°. { sum of all angles of triangle is 180°}

150°+y=180°

y=180°-150°

y=30°

angle x+30°=180°

angle x=180°-30°

angle x=150°

Answer 2

Answer:

Hope it helps......

y = 70° ( Opposite angles are equal )

y + x = 180° ( Linear Pair )

70° + x = 180°

x = 180° - 70°

x = 110°
