Question

7. Two angles of a triangle measure 30° and 55° respectively. Find the measure of the third angle also state what type of a triangle is it.

please it argent
​

Answer 1

Sum of angles in a triangle is 180
Let the third angle be x
Therefore, x+30+55=180
x=180-85
So x=95
All the angles of the triangle are different i.e; Scalene triangle

Answer 2

Step-by-step explanation:

let the third angle be x

By angle sum property of triangle

30° + 55° + x = 180°

85° + x = 180°

x = 180° - 85°

x = 95°

• Since one angle of the triangle is more than 90°, so it is an Obtuse angled triangle.
• Since all angles are unequal, so it is a Scalanne Triangle.
