You know that the sum of the interior angles in a triangle is 180
we will add all the angles,
(x+8)+(2x-8)+(3x-12)=180
x+8+2x-8+3x-12=180    8 and -8 cancel out 
6x-12=180
6x=180+12
6x=192
x=192/6=32
x=32

Using the equation representing the height of the firework (h = -16t2 + v0t + h0), algebraically determine the extreme value of
lubasha [3.4K]
-16t^2 + v0t + h0

=  -16(t^2 - 1/16 v0t)  + h0
 = -16 [(t - 1/32v0)^2 - (1/32 v0)^2 ) + h0
 = -16(t - 1/32v0)^2 + 1/64 (v0)^2 + h0   which is the vertex form 

The vertex  is at the point (1/32v0, 1/64 (v0)^2)

1/32v0  represents the time  when the firework is at its maximum height and 1/64 (v0)^2  is this maximum height

Justin builds a triangular fenced area for his dog called Triangle ABC. If AB = 17 ft and BC = 8ft, and angle C is a right angle
Anika [276]

The missing side of the fence measures 15 ft

The perimeter of the fence is 40 ft

The area inside the fenced in section is 60 ft²

The fence is triangular and a right triangle.

<h3>Right triangle:</h3>

A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.

c² = a² + b²

17² - 8² = b²

b = 15 ft

AC = 15 ft

perimeter of the triangle = 15 + 8 + 17 = 40 ft

Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²

Therefore,

The missing side of the fence measures 15 ft

The perimeter of the fence is 40 ft

The area inside the fenced in section is 60 ft²
