(Geometry), homework pleaseeeee help. Will rate brainliestttt

Answer
13. D
14. B
15. A
Solution
13. The answer is D since all of the sides are equal.
The answer is not scalene (B) because all of the sides are equal and scalene is the term that describes a triangle which does not have any equal sides.
The answer is not isosceles (C) because all of the sides are equal and isosceles is the term that describes a triangle which has two equal sides.
The answer is not straight (A) because the sides do not measure to 180°.
14. We are solving for x so we simply do:
[tex] 114+47= 161 [/tex]
[tex] 180-161= 19 [/tex]
Therefore, [tex] x=19 [/tex] which is why the answer is D.
Important terms to remember
Equilateral- This term applies to a triangle when all sides are equal.
Scalene- This term applies to a triangle when none of the sides are equal.
Isosceles- This term applies to a triangle when only two sides are equal.
Straight- This term applies to angles that are only 180°
