Question

What is the measure of the third angle of triangle if the other two measure 40

Answer 1

Step-by-step explanation:

We know that the sum of the interior angles of a triangle is 180

∘

. Let third angle in all the given triangles be x

∘

. Therefore 80 ∘ +40∘ +x ∘ =180 ∘

x ∘ =180 ∘ −120 ∘

x ∘ =60 ∘

Answer 2

Answer:

100

Step-by-step explanation:

all the measures of angle of a triangle =180

let the measure of the third side be X

40 +40+x=180

80+x=180

x=180-80

x=100
