Question 249678
"The size of the smallest angle of a triangle is 30% of the size of the largest angle, and the size of the third angle is 20degrees more than the smallest angle. Find the size of each angle."
------------------------------
Let the largest angle have size = "x":
Then smallest angle has size 0.30x.
And size of third angle = "0.30x+20"
------------------------------------------
Equation:
x + 0.30x + 0.30x+20 = 180
1.6x = 160
x = 100 degrees (largest angle)
0.30x = 30 degrees (smallest angle)
0.30x + 20 = 50 degrees (3rd angle)
