The Awnser is A 1 yard of fabric
Answer:
30 is the perimeter i think 2 x 5 = 10 + 2 x 4.5 = 10 x 2 = 20 so 20 + 10 = 30
I think the area is 45, 5 x 4.5 = 22.5 and 2 x 22.5 = 45
Wait for more responses if needed please.
The dimensions would be 28.9 for the steel length and 28.8 for the pine boards, for a total cost of $403.40.
To maximize area and minimize perimeter, you want a figure that is as close to equilateral as you can get. Therefore we take the square root of our area:
√833 = 28.9.
Dividing 833/28.9 we get 28.8.
We want to use the shorter side, 28.8, for the pine boards, as they cost more. 28.8*2*6 = 345.60.
The cost of the steel side is given by 28.9*2 = 57.80.
Together it costs 345.60+57.80 = 403.40.
Answer:
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal interior angles
In this problem
The triangle ABC is an isosceles triangle, because
m∠A=m∠C
therefore
AB=BC
substitute the given values
solve for x
<em>Find the length of side AC</em>
substitute the value of x
