<p>I don't understand how the answer for this problem is 80 degrees can someone explain it to me please.
10.
The angles of a triangle are in the ratio of 2:3:4. What is the degree measure of the largest angle?</p>
<p>They are in the ratio 2x : 3x : 4x. Remember if you add up all the angles in a triangle it equals 180.
So 2x + 3x + 4x = 180
9x = 180
x = 20
now to find largest angle it would be the 4x one so 4(20) = 80</p>
<p>Thanks Gyro. Your a beast!!</p>
