17. in an isosceles triangle, the base is 17 less than 3 times one of the legs. if the perimeter is 33 in, find the length of each leg and the length of the base. show all work!

Let x = one leg. the base is then 3x-17. the perimeter I'd given by x+x+3x-17=33

5x-17=33
5x=50
x=10
2 legs are 10 each and base is 13

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
