Question 1070184: The largest angle of a triangle is 5 times the size of the smallest, and the middle angle is 3 times the size of the smallest. What are the three angle measures?
The smallest angle of a triangular sunshade measures 11 degrees less than the middle-sized angle. The largest angle measures 11 degrees more than twice the middle-sized angle. What are the angle measures?
Thank you!
You can put this solution on YOUR website! First one has angles x, 3x, and 5x. They add to 180 (x is the smallest angle)
9x=180
x=20 degrees
3x=60 degrees
5x=100 degrees
-------------------------------
middle angle is x
smallest is x-11
largest is 2x+11
They all add to 180
x+x-11+2x+11=180
4x=180
x=45 degrees (middle)
smallest is 34 degrees
largest is 101 degrees
