Question

Construct an isosceles triangle whose
triangle whose base is 9 cm and altitude is 8 cm. Then construct
ingle whose sides are 3/4 of the corresponding sides of the first
isosceles triangle​

Answer 1

Answer:So you have length

l=legs and b=base

the first perimeter is 2l+b=8.5 since there are 2 legs

the second perimeter is 4l+b=15.5 since the legs are now 2l long instead of l

subtract the top problem from the bottom problem

(4l+b)-(2l+b)=15.5-8.5

2l=7 so l=3.5

if l=3.5 and 2l+b=8.5, 7+b=8.5, so b=1.5

check by plugging it into the second perimeter

4(3.5)+1.5=15.5-->14+1.5=15.5
