the ratio of the measures of three sides of a triangle are 5:7:8 find the angle measures
----------------
Find the 3 angles.
Use the Cosine Law to find the 1st angle.
Use sides of 5, 7 & 8.
-----------------
a = 5
b = 7
c = 8
---
5/sin(A) = 7/sin(B) = 8/sin(C)
The ratio of the angles is not the ratio of the sides.
