Answer 1

Explanation:

Explanation:

ANSWER:-

Given that:-

One angle is 30°

Another angle is 55°

Find out:-

The third angle

Let's Do!

Theorem applied - Angle sum property of a Triangle.

The sum of angles of a Triangle is equal to 180°.

$30 + 55 + x = 180$

$85 + x = 180$

$x = 180 - 85$

$x = 95$

So, the third angle is 95°.

Now,:-

There are 3 types of Triangle

Equilateral - 3 sides same and angles equal 60°

Isosceles 2 sides same, 2 angles same

Scalene - No side or angle same.

As we can see no angles are same, it is a scalene triangle.
