Question

Arpita estimated the back of her arm chair to be an angle of 125 degree to the seat of the chair what type of an angle has she estimated it to be?​

Answer 1

Given:

Given that, Arpita estimated the back of arm chair which is an angle of 125 degrees.

To find:

We need to identify what type of an angle it is.

Solution:

According to the question, the angle is $125^\circ$.

Before identifying the angle, we should know about some angles.

• If a angle is between $0^\circ \ \text{and} \ 90^\circ$, it is known as Acute angle.
• If a angle is equal to $90^\circ$, it is known as Right angle.
• If a angle is above $90^\circ$, it is known as Obtuse angle.

The given angle in the question is equal to $125^\circ$.

As, it is above $90^\circ$, it is known as Obtuse angle.

Therefore, the angle estimated is an Obtuse angle.
