Hi there!

You would use open intervals.

In the given inequality, the "<" sign is used, which means "greater than".

Open intervals would be used unless the inequality uses "≤" or "≥", which

mean "equal to or greater/less than". Closed brackets would be used in this

instance.

How many triangles are formed by the angles and sides-unique triangle, no triangle, or many triangle

kirill115 [55]

No triangle formed

Solution:

Given data:

One angle is 45°

Another angle is 108°

One side is 7 cm

To find how many triangles are formed for the given data.

Let the unknown side of a triangle be x°.

Sum of all the sides of a triangle = 180°

45° + 108° + x° = 180°

⇒ x° = 180° – 45° – 108°

⇒ x° = 27°

There is no such angle can be formed with 27° in the given image.

Hence there is no triangle can be formed.
