Question

find the unknown angle and classify the triangle on the basis of angle .; <A=65°,<B=35°
​

Answer 1

Answer:

<A + <B + <C = 180 The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.

So <C is unknown. <C = 180 - 65 - 35 = 80

Step-by-step explanation:

Answer 2

Answer:

Angle C= 80°

Type of Triangle= Scalene Triangle

Step-by-step explanation:

Given, Angle A= 65°

Angle B= 35°

Angle C= ?

So,

Angle A+ Angle B+ Angle C= 180° [Angle Sum Property]

65°+35°+ Angle C= 180°

100°+ Angle C =180°

Angle C= 180°-100°

            = 80°

-All the angles are different therefore, it is an scalene triangle
