Steve made a sign for his room that is shaped like a triangle. it is 4.5 feet long and 3 feet high. he wants to make another sign that is shaped like a triangle and similar to the first sign. the new sign will be 4 feet high.

part a

write a proportion that steve can use to find the length, x, of the new sign.

part b

what is the length, in feet, of the new sign? make sure to show your work and explain your reasoning.

PART A : =

PART B : 5.9 FEET

Step-by-step explanation:

Length of the first sign = 4.4 feet

height of the first sign = 3 feet

Length of the second sign = x feet

height of the second sign = 4 feet

If two shapes are similar , then the ratio of their sides are equal,

That is ;

=

PART A

=

PART B

=

cross multiplying , we have

3x = 4.4 x 4

3x = 17.6

Divide through by 3

x = 17.6/3

x = 5.86666666666667

x≈ 5.9 feet

Therefore , the length of the new sign is 5.9 feet
