Question

Need alot of help please!!!

Answer 1

A=x
B= 2x
C=3x
If you add them up =
6x =180
÷6 both sides
x=30
A=30
B=60
C=90
one angle is 90 degrees so the triangle is classified as a right triangle

Answer 2

A right triangle.

∆ = angle in my explanation.

All the angles in a triangle add up to 180°. This means in this triangle m∆A + m∆B + m∆C = 180°.

Substitute what you have and it becomes x + 2x + 3x = 180°. Add the like terms, and then 6x = 180°. Divide by 6, and we have x = 30°.

Now that means m∆A = 30°, m∆B = 2(30) or 60°, and m∆C = 3(30) or 90°.

A 90° angle is a right angle, so therefore, the triangle classified by it's angle(s) is a right triangle.

No problem!
