Answer:
Acute
Step-by-step explanation:
Note the definitions:
Obtuse: At least one of the angles are greater than 90°
Equilateral: All angles are congruent & equal to 60°
Acute: All angles are less than 90°
Right: At least one angle is equal to 90°
In this case, the triangle is a D) acute, for it fits the requirement for being an acute... all angles are less than 90°.

Where is the rest of the question? What is it asking?
Step-by-step explanation:
Well I guess if you want to change up the equation you can do 7 * X = Y
The * is just a multiplecation symbol if you didnt know
