Answer:
C.
Step-by-step explanation:
A triangle has a total of 180 degrees of angles. This means that if you add the angles of a triangle, it will equal 180. For example, 90+45+45 gives you 180, and a right triangle. You can find the right answer by looking at which sum of angles equals 180. So,
90+76+104=280 Wrong.
90+45+90=225 Wrong.
<u>90+38+52=</u><u>180</u><u> Right HOORAY.</u>
90+38+104=232 Wrong.
The sum of the angles of a triangle will always equal 180, so remember that. No matter what shape or size, if it isnt 180, its not a triangle.
