Question

Two isosceles triangles have the same base length. The equal sides of one triangle are 4.25 times as long as the equal sides of the other. algebraically calculate the lengths of the sides of the triangles when their perimeters are 38cm and 116cm

Answer 1

B= 5

Explanation:

Two isosceles triangles have the same base length. The legs of one of the triangles are twice as long as the legs of the other. Find the lengths of the sides of both triangles if their perimeters are 23 cm and 41 cm.

----------------

s = length of legs of smaller triangle

2s = that of taller triangle

b = base

23 = b + 2s

41 = b + 4s

------------- Subtract

-18 = -2s

s = 9

------

b = 5
