Question

The angles of a triangle are in the ratio 1:5:6. This triangle is

a. acute
b. obtuse
c. isosceles
d. right
e. equilateral

the answer is D. right triangle.

Answer 2

Right

Explanation:

The angles of a triangle add up to 180°.

1+5+6 = 12.

180/12 = 15

So, you multiply 1, 5, and 6 by 15 to get 15, 75, and 90

Because there is a 90 degree angle, it is a right triangle.
