the area of a triangle is 384 square feet. If its base is 8 feet longer than its altitude, find the length of the base and the a

REY [17]

A=1/2bh
b=8+h
A=384

384=1/2(bh)
times 2
768=bh
sub
768=b(8+b)
768=8b+b^2
minus 768 both sides
0=b^2+8b-768
factor
0=(b-24)(b+32)
set to zero
b-24=0
b=24

b+32=0
minus 32
b=-32
false, legnths cannot be negative

b=24
24=8+h
minus 8
16=h

base=24ft
altetude=16ft

Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.

Answer:

x = 6

y = 3

Step-by-step explanation:

Give triangle is a right triangle.

By applying sine ratio in the given triangle,

sin(60)° = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3}}{2}=\frac{3\sqrt{3}}{x}$

x = 6

Now we take the cosine ratio in the given triangle,

cos(60)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{1}{2}=\frac{y}{x}$

y = $\frac{x}{2}$

y = $\frac{6}{2}=3$

Therefore, x = 6 and y = 3 will be the answer.
