Answer:

The triangle is acute.

Step-by-step explanation:

-According the to following triangle, the angles are acute, because acute angles less wider and they measure less than 90°.

-The reason why the triangle is not a right or obtuse, is because right angles are angles that measure exactly 90°, and obtuse angles are angles that are much wider and they measure greater than 90°.

Answer:

$m\angle A=21$ °

$m\angle B=125$ °

$m\angle C=34$ °

Step-by-step explanation:

Let the measure of angle C be $x$ °.

Given:

In triangle ΔABC,

$m\angle A$ is thirteen less than $m\angle C$ and $m\angle B$ is eleven less than four times $m\angle C$ . This gives,

$m\angle A = x-13$

$m\angle B=4x-11$

Also, $m\angle C=x$

Now, for a triangle, the sum of all its interior angles is equal to 180°.

Therefore, $m\angle A + m\angle B + m\angle C=180$

Plug in all the values and solve for x. This gives,

$x-13+4x-11+x=180\\6x-24=180\\6x=180+24\\6x=204\\x=\frac{204}{6}=34$

Therefore, measure of angle C is 34°.

Measure of angle A is, $m\angle A=x-13=34-13=21$ °.

Measure of angle B is, $m\angle B=4x-11=4(34)-11=136-11=125$ °.
