Question

In triangle ABC, angle A=35, angle B =65 then the measure of angle C is

Answer 1

Answer:

angle C = 100 degrees

Step-by-step explanation:

Always in a triangle, the sum of the three angles is 180 degrees.

Given: Angle A = 35 degrees

          Angle B = 65 degrees

To find: Angle C

Angle A + Angle B + Angle C = 180 degrees.

35 + 65 + Angle C = 180 degrees

100 + Angle C = 180 degrees

Angle C = 180 - 100 degrees

Angle C = 80 degrees

Answer 2

Given : In triangle ABC, angle A=35, angle B =65

To Find :  the measure of angle C

Solution:

m∠A = 35°

m∠B = 65°

m∠C = ?

Using triangle angle sum theorem that sum of measures of all the angles of a triangle is 180°

=> m∠A + m∠B + m∠C  = 180°

Substituting values of m∠A = 35° and  m∠B = 65°

=> 35°  +  65° + m∠C  = 180°

=> 100° + m∠C  = 180°

=>  m∠C  = 180° - 100°

=> m∠C  =  80°

Hence the measure of angle C is  80°
