Answer:

39

Step-by-step explanation:

all angles of a triangle equal to 180, so you just have to subtract those two known angles from 180, and you will get the answer.

Question : -

Find the value of angle x .

Given : -

  • First angle = 45°

  • Second angle = 96°

  • Third angle = x°

To Find : -

  • We have to find the value of x .

Concept : -

The concept of this question belongs to angles of triangle . We know that the sum of all the three angles of triangle is 180°.

So let's get started : -

As we know that all the angles of triangle is equal to 180° . So :

  • 1st angle + 2nd Angle + 3rd Angle = 180°

  • 45° + 96° + x° = 180°

  • 141° + x° = 180°

  • x° = 180° - 141°

  • x° = 39°

Therefore , angle x is of 39° .

Verifying : -

  • 45° + 96° + 39° = 180°

  • 141° + 39° = 180°

  • 180° = 180°

  • L.H.S = R.H.S

  • Hence, Verified .

Thus, our answer is valid .
