Question

two angles of an obtuse angle triangle are are 40 degree and 35 degree find the measure of the third angle​

Answer 1

Answer:

The third angle is 105°.

Step-by-step explanation:

Solution :

The triangle is an - Obtuse Triangle

One angle = 40°

Second angle = 35°

We have to get the value of the third angle. As mentioned in the question, the triangle is an Obtuse Triangle which means the third angle is more than 90° and less than 180°.

Let the third angle be y.

According to the Angle sum Property of triangle, sum of all the angles is 180°.

⇒ 40° + 35° + y = 180°

⇒ 75° + y = 180°

⇒ y = 180° - 75° [tex][/tex]

⇒ y = 105°

Third angle = 105°

Therefore, the third angle is 105°.

Answer 2

Answer:

Given :-

• Two sides of triangle are 40 and 35 degree

To Find :-

Third side

Solution :-

As we know that sum of all angles in a Triangle is 180⁰.

Let the third side be x.

$\sf \implies 40 + 35 + x = 180$

$\sf \implies \: 75 + x = 180$

$\sf \implies \: x \: = 180 - 75$

$\frak \pink{x \: = 105 \degree}$

Therefore, the third angle is 105°.
