Question

Two angles of a triangle are 35° and 40° then third angle is

Answer 1

Answer:

as we already know that the sum of all the angles of a triangle is 180°

let the third angle be 'x'

so,

35+40+x=180°

75+x=180°

x=180-75

x=105°

therefore the third angle of the triangle is 105°

Answer 2

Answer:

• 3rd Angle of the Triangle = 105°

Step-by-step explanation:

In order to solve this question, you should know about Angle Sum Property Of A Triangle.

Angle Sum Property of A Triangle [ASP Of Triangle]

• This Property states that sum of all angles of a Triangle is 180°.

• It means that$\angle 1$ + $\angle 2$ + $\angle 3$ = 180°

Let's Do It!!

Given

Two angles of a Triangle are

• 35° and 40°

• Now, Let's Assume the 3rd angle as x

• Now, use ASP

• 35 + 40 + x = 180°

• 75 + x = 180°

• x = 180 - 75

• x = 105°

• So, 3rd Angle of the Triangle = 105°
