Question 535680
The angles of a triangle equal 180 degrees. The ratio is 2:3:4, so we must find what the 'multiplier' will be to determine the angles measurement.

We have three numbers 2, 3, and 4 all equaling to 180 degrees.
Let x represent your multiplier.
2x+3x+4x=180
9x=180
x=20

Now replace x----
2(20)=40(first angle)
3(20)=60(second angle)
4(20)=80(third angle)

And as you can see all three angles equal 180 degrees. Hope this helps:)
