Question

The two interior opposite angles of an exterior angle of a triangle are 50° and 70°. Find the measure of the exterior angle.​

Answer 1

Answer:

Easy peesy :)

we know sum of two interior angles of a triangle is the exterior angle

We know 50° and 70° are the two opp. interior angles of a triangle

just add them

50°+70°=120° is the answer

hope it helps you :)

The two interior opposite angles of an exterior angle of a triangle are 50° and 70°. Find the measure of the exterior angle.

$\huge{\underline{\mathtt{\red{A} \pink{N} \green{S} \blue{W} \purple{E} \orange{R}}}}$

$\huge\boxed{\blue{Given :}}$

➣ One interior opposite angle of an exterior angle of a triangle = 50°

➣ Another interior opposite angle of an exterior angle of a triangle = 70°

$\huge\boxed{\red{To \: Find :}}$

➣ Measure of the exterior angle of the triangle

$\huge\boxed{\pink {Solution :}}$

➪ Sum of interior opposite angles of a triangle is equal to the exterior angle of the triangle

➪ Exterior angle = Sum of its interior opposite angles

⇒ Exterior angle = 50° + 70°

⇒ Exterior angle = 120°

➦ So, the measure of the exterior angle of the triangle is 120°
