Answer 2

Question :-

Given the triangle STU, find the exterior angle.

A. 120°

B. 50°

C. 70°

D. 180°

____________________

Solution :-

Given Information :-

• Measure of ∠S = 70°
• Measure of ∠T = 50°
• Line SUY is a Straight Line.

To Find :-

• Exterior angle of triangle STU = ∠TUY

Formula Used :-

• ∠TUY = ∠S + ∠T (Reason :- Exterior angle = sum of the two opposite interior angles)

Calculation :-

Simply substituting the values of ∠S and ∠T in the formula, We get,

⇒ ∠TUY = 70° + 50°

⇒ ∠TUY = 120°

____________________

Final Answer :-

• Angle TUY (exterior angle of triangle STU) measures 120°
• Since 120° is given in option A. Therefore, Option A. 120° is the correct answer.
