Question

The measures of an equal side and the base of an isosceles triangle are in the ratio 8 : 5. If the perimeter of the triangle is 105 mm the measures of its sides are:

Answer 1

Answer:

40,40,25

Step-by-step explanation:

equal side:base=8:5

2 sides are equal

so two sides are 8x and 8x

another side be 5x(as given in the ratio)

perimeter of the isosceles triangle=105mm

atq=8x+8x+5x=105

21x=105

x=105/21

x=5mm

sides are 40,40 and 25.
