Question

(EASY)(BRAINLIEST)Which of the four angles marked on the picnic table is obtuse?

Answer 1

The angle that is obtuse is 1, because it is greater than 90°.

Hope this helps and have a nice day:)

Answer 2

Answer:

$\angle 1$ is an obtuse angle

Step-by-step explanation:

An angle is a figure formed by two sides of a triangle sharing the common vertex.

Basically, in a triangle , an angle refers to a amount of turn by the sides of the triangle around a common vertex.

An acute angle is angle whose measure is less than $90^{\circ}$ and an obtuse angle is a angle whose measure lies between $90^{\circ}$ and $180^{\circ}$.

A right angle is equal to $90^{\circ}$

A straight angle is equal to $180^{\circ}$

A complete angle is equal to $360^{\circ}$

Here, from the figure we observe that $0^{\circ}\,\,< \,\,\angle 2\,,\,\angle 3\,,\,\angle 4\,\,< 90^{\circ}$

So, angles $\angle 2\,,\,\angle 3\,,\,\angle 4$ are acute angles.

$90^{\circ}\,\,< \angle 1\,\,< 180^{\circ}$

So, $\angle 1$ is an obtuse angle.
