Answer:
32
Step-by-step explanation:
This is an equilateral triangle, the 3 sides are equal.
Also, that means 3 angles are equal.
Given the 2 angles, we can say:
2x - 4 = 5y
Also, the angle is "5y" as they are equal.
Sum of 3 angles of a triangle is 180, so we can write:
2x - 4 + 5y + 5y = 180
2x + 10y - 4 = 180
2x + 10y = 184 [Equation 2]
From the first equation we can solve for y:
Now, we plug this into Equation 2 and find x:
So x is 32
AccordingAccording to the floor plan, the one that is closest to the total length, in feet, of the walls that Kamal should quote to the artist is: 58.65.
<h3>Length</h3>Let the length of hypotenuse be x
Using Pythagorean theorems
x²=(19-15)²+12²
x²=16+144
x²=160
x=√160
x=12.649
x=12.65 (Approximately)
Hence:
Total length:
Total length=12.65+15+12+19
Total length=58.65
Therefore according to the floor plan, the one that is closest to the total length, in feet, of the walls that Kamal should quote to the artist is: 58.65.
