Question

In triangle ABC, angel A=30°, angel B= 45° then find angel C?​

Answer 1

Answer:

Measure of <C = 105°

Step-by-step explanation:
Measure of <A = 30°
Measure of <B = 45°

By using angle sum property of a triangle,
⇒ <A + <B + <C = 180°

⇒ 30 + 45 + <C = 180° ⇒ 75 + <C = 180

⇒ <C = 180°-75° = 105°

∴ The measure of <C is 105°


Hope this helps!

Answer 2

Given:

In the triangle ABC,

Angle A =30°

Angle B = 45°

To find:

Here, we need to find the value of Angle C.

Solution:

Angle of triangle = A + B+ C = 180°

∴ Angle of triangle ∠A + ∠B + ∠C = 180°

Here, we need to put the values

Angle A = 30°

Angle B = 45°

Let's substitute and find the answer

Angle of triangle ∠A + ∠B + ∠C = 180°

                             30° + 45° + ∠C = 180°

                                      75° + ∠C =180°

                                              ∠C = 180° - 75°

                                               ∠C =  105°

∴ The value of Angle C is 105°
