Question

If the measure of two angles of a triangle are 40° and 50° respectively. Find the remaining angle of the triangle. What type of the triangle is it ?​

Answer 1

Answer:

90°

Step-by-step explanation:

To find another angle, add the two other angles and substract it from 180°

= 40° + 50°

= 90°

= 180° - 90°

= 90°

All the three angles of this triangle are not the same.

Thus, this triangle is a Scalene Triangle.

Answer 2

Given :

• two angles of a triangle are 40° and 50°

To find :

• the remaining angle of the triangle.
• the type of triangle

Solution :

⇒ Let's find the remaining angles of the triangle. Let the remaining angle be x.

• The total sum of angles in a Triangle = 180°.

→ 180° = 40° + 50° + x

→ 180° = 90° + x

→ x = 180° - 90

→ x = 90°

∴ x = 90°

• Therefore, the remaining angle of the triangle is 90°.

⇒ Now, let's find out which type of triangle it is.

• It is an Obtuse Triangle.
• Because the triangle has one 90° angle.
