Question

find x and y in figure​

Answer 1

Answer:

y ∘ +140 ∘

=180 ∘ (Supplementary nagles made on straight line)

y=180 ∘−140 ∘

=40 ∘x ∘=y ∘+30 ∘

(Exterior angle of triangle is equl to sum of two interior opposite angles)

x=40 ∘ +30 ∘

x=70 ∘

Answer 2

Answer:

y = 40° & x = 70°

Step-by-step explanation:

y° +140° =180° (Supplementary nagles made on straight line)

y=180° −140° =40°

x° =y° +30°

(Exterior angle of triangle is equl to sum of two interior opposite angles)

x=40° +30°

x=70°
