Answer:
The triangle is:
A. Scalene.
E. Acute
Explanation:
Scalene triangle--
A triangle is said to be scalene if the length of all the three sides of a triangle are different.
Right triangle--
A triangle is said to be a right triangle if one of the angle is right angle i.e. measure of one of the angle is: 90 degrees.
Equilateral triangle--
A triangle is said to be equilateral if all of the sides of a triangle are equal.
Obtuse triangle--
A triangle is said to be obtuse if measure of one of the angle is more than 90 degrees but less than 180 degrees.
Acute triangle--
A triangle is said to be acute triangle if the measure of all the three angles of a triangle are less than 90 degrees.
Based on the diagram we observe that all the sides of a triangle are different and all the three angles of a triangle are less than 90 degrees.
Hence, the triangle is scalene and it is a acute triangle.
