Question

Two angels of a triangle measure 30° and 55° respectively. Fine the measure of the third angel. Also state what type of a triangle is it ​

Answer 1

let the third angle= x

30°+55°+x = 180° ( angle sum property)

85°+x = 180°

x= 180°-85

x= 95

I think it is acute angle.

Answer 2

Question:-

• Two angels of a triangle measure 30° and 55° respectively. Fine the measure of the third angel. Also state what type of a triangle is it .

Given:-

• The measures of triangle as 30° and 50°.

To find:-

• The measure of third angle if triangle.

Solution:-

Let the measure of third angle be x.

⇰ 30°+50°+x=180° ___(angle sum property )

⇰85°+x=180°

⇰ x= 180°-85°

⇰x=95°

$\boxed{ \underline{ \red{ \mathfrak{Therefore \: the \: measure \: of \: third \: angle \: is \: 95°}}}}$

The triangle is scalence triangle.

Why?

A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures
