Question

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 100 degrees more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180 degrees to find the measure of each angle.

The measure of the smallest angle is __ degrees.
The measure of the second largest angle is __ degrees.
The measure of the largest angle is __ degrees.

Answer 1

2x+x+(100+x)=180

Answer 2

calculate x and you get the answers

Answer 3

is the measure in degree or in radian ?

Answer 4

in degrees

Answer 5

x=20, and so smallest is 20

Answer 6

2x=40 second larggest, and the largest is (100+x)=120

Answer 7

So plug 20 into x ?

Answer 8

yes, as you can see above how i found x

Answer 9

Oh, I understand.
