Question

Some one help me I don’t get this

Answer 1

acute

Explanation:

this is an acute triangle because all angles are less than 90 degrees

it is not obtuse because no angle is over 90 degrees

it is not equiangular because the angles are not equal to each other

and it is not right because there is no right angle

Answer 2

Acute

Explanation:

Triangles can be classified by the size of their angles.

Angle Classification

Angles can be classified into 3 sizes: acute, right, and obtuse.

• Acute triangles are the smallest angles. Their measurements are less than 90° (x < 90).

• Obtuse angles are the largest angle. Their measurements are greater than 90° (x > 90).

• Finally, right angles must have a measurement of exactly 90° (x = 90). Any larger or smaller and it is not a right angle.

Triangle Classification

Triangles are classified by their largest angle. If the largest angle is obtuse, then it is an obtuse triangle. If there is a right angle, then it is a right triangle. If the largest angle is an acute angle, then it is an acute triangle. Finally, there is one special classification that technical falls under acute angles. If all of the angles are equal (meaning they are all 60°), then it is an equiangular triangle.

The triangle in the picture has 3 angles that are all under 90°. The largest angle is 76°. Since this is an acute angle, it is an acute triangle.
