The two interior opposite angles of an exterior angle of a triangle are 30° and 40°. 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 = 30°

➣ Another interior opposite angle of an exterior angle of a triangle = 40°

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

➣ 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 = 30° + 40°

⇒ Exterior Angle = 70°

➦ So, the measure of the exterior angle of the triangle is 70°
