Question

Classify triangle ABC by its angles if m 11 years ago

Answer 1

the three angles add to 180 degrees,so,

x+2x+3x = 180

solve for x

Answer 2

since it equals to 180 it'll be an obtuse triangle?

Answer 3

No, the sum of the interior angles of any triangle is 180 degrees.

Answer 4

Solve for x and then substitute that value back into each of the terms.

Answer 5

That will tell you the measurement of each of those angles. Then you can make a determination of the type of triangle.

Answer 6

I got 5x/5 equals 180/5 .... then substituted <M= 36 , <b= 72 , <c= 108

Answer 7

Yes, so now you can classify it. What type is it ?

Answer 8

obtuse

Answer 9

Yes

Answer 10

you should have 6x = 180

NOT 5x = 180
