Answer 1

Answer:

$\ 1,826.81$

Step-by-step explanation:

The correct question is

Triangle shown is an equilateral triangle with a bottom base of 15 ft

we know that

An equilateral triangle has three equal sides and three equal interior angle (each measure is 60 degrees)

step 1

Find the area of triangle

Applying the law of sines

$A=\frac{1}{2}(15^2)sin(60^o)= 97.43\ ft^2$

step 2

Find the cost

Multiply the area of the window by the unit rate of $18.75 per square foot

$97.43(18.75)=\ 1,826.81$
