Scott needs to replace a broken window at his house. The window is shaped like a triangle with
dimensions shown below. If glass costs $18.75 per square foot, how much with the replacement
window cost?
(Triangle shown is isoceles with a bottom base of 15. All other measurements are unknown)

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

step 2

Find the cost

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

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
