4.7
30°
30°
120°
2.7
2.7
A) acute isosceles
B) acute scalene
C) obtuse isosceles
D) right isosceles

Answer 1

The triangle given has two sides of length 4.7 and one side of length 2.7. The angles are 30°, 30°, and 120°. It is classified as an obtuse isosceles triangle.

Step-by-step explanation:

The triangle given has two sides of length 4.7 and one side of length 2.7. The angles are 30°, 30°, and 120°.

To classify the triangle, we need to consider both its sides and angles.

In terms of sides, since two sides of the triangle have the same length (2.7), it is classified as an isosceles triangle.

In terms of angles, an angle measuring 120° is an obtuse angle.

Therefore, the classification of the triangle is obtuse isosceles (Option C).
