A triangle has one angle that measures 39 degrees, one angle that measures 104 degrees, and one angle that measures 37 degrees. What kind of triangle is it? *

Obtuse triangle

Step-by-step explanation:

An obtuse triangle is a kind of triangle that has one of its three angles to be greater than 90 degrees but less than 180 degrees.

For instance: Angle ABC + Angle BAC + Angle ACB = 180° ( where Angle ABC = 39°, Angle BAC 104°, and Angle ACB = 37°)

On the other hand, a right-angled triangle has 90° as one of its angles, while acute-angled triangle has all its three angles less than 90°

Thus, since one of its angles in the triangle is 109° it is a obtuse triangle.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
