in an oblique triangle the sides are 5, 4, and 3. find the largest angle.


Sagot :

if the sides of a triangle are in the ratio    3,4 & 5
it is not a oblique triangle, it is a right triangle
the multiplies of the sides are also right triangles
ex:          6,8 &10        / multiply by  2            and  so on
the largest angle =  90°
use Law of Consine . the largest angle is 90 and the opposite angle 90 is 5
