The measure of the 3 angles in a triangle are (4x) degrees,(3x-3) degrees, and (5x+3)degrees. Please write an equation, solve fo
r x, and determine the measure of each angle. Please show work and thanks for helping

This is a good one!
So we know that a triangle's angles must add up to 180 degrees. Therefore, we can say that:
(3x - 3) + (5x + 3) + (4x) = 180.
This can be rewritten as 12x = 180.
Divide each side by 12 to get x alone, you get:
x = 15
Time to plug n' chug.
4x = 60, 3x - 3 = 42, 5x + 3 = 78
Boom!

12/18 = 8/x <=> 2/3 = 8/x <=> x = (3*8)/2 = 12;
7.1 is ten times smaller than 71
Answer:
Sam is correct
Step-by-step explanation:
The third side is the one with greatest length. To make a triangle the other two lengths have to be greater than the greatest one when combined.
