Question

Please help me find out the answer I am request you to find out the answer if you don't know the answer don't answer it and please do all the questions.​

Answer 1

Answer:

⇒ 1.  Sum of 3 angles Of Triangle is 180°

Here Given,

57°, 61° and 62°

Sum = 57 + 61 + 62

= 180°

And

180° = 180°

So,

It must be a Triangle Δ

⇒ 2.  The angles must be

90°, 45° and 45°

Because,

Sum of 3 angles Of Triangle is 180°

And

Sum of 45° and 45°

= 90°

And

90° = 90°

So,

Answer 2

Answer:

Q1 .

Solution:

Given:

57° , 62° , 61°

We know that:

Sum of three angle of triangle is 180°.

Therefore, 57° + 62° + 61°= 180°

=> 180° = 180°

THEREFORE, IT IS A TRIANGLE .

Q2.

Solution:

ACC . to Q

the angle must be

90° , 45° , 45°

Because 90°= 45° + 45°

therefore, The angles are 90° , 45° , 45°
