Answer:

x = 19.6

Step-by-step explanation:

By applying cosine rule in ΔBCD,

cos(30)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{BC}{BD}$

$\frac{\sqrt{3}}{2}=\frac{BC}{16}$

BC = $8\sqrt{3}$

Now, by applying sine rule in ΔBAC,

sin(45)° = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$\frac{1}{\sqrt{2}}=\frac{AB}{BC}$

$\frac{1}{\sqrt{2}}=\frac{x}{8\sqrt{3}}$

x = $8\sqrt{6}$

x = 19.59

x ≈ 19.6

A chocolate chip cookie recipe requires one and three quarters cups of flour to one cup of chocolate chips. If four and two thir

nikitadnepr [17]

1 cup of chocolate chips for every 1and 3/4 cup of flour

so divide 4 and 2/3 x 1 and 3/4

turn them both into fractions

4 2/3 = 14/3

1 3/4 = 7/4

14/3 / 7/4 = 14/3 x 4/7 = 56/21 = 2 and 2/3 cups of chocolate chips are needed

The figure shown is made up of triangle ABF and rectangle BCDE. The area of the figure is 90 square feet. If AB=BC=BF=FE, find A

Ludmilka [50]

The complete question in the attached figure

let
x-----> distance AB
so
AC=2x

we know that
area of the figure=area of triangle+area of rectangle
area of the figure=90 ft²

step 1
find the area of triangle
$A=b*h/2$
b=x
h=x
so
$A=(x*x)/2$
Area of triangle=x²/2 ft²

step 2
find the area of rectangle
$A=b*h$
b=2x
h=x
$A=(2x)*x------\ \textgreater \ A=2x^{2}$
area rectangle=2x²

step 3
find value of x
area of the figure=(x²/2)+2x²
area of the figure=90 ft²
90=(x²/2)+2x²-----> multiply by 2 both sides----> 180=x²+4x²
5x²=180-----> x²=36-----> x=6 ft

AC=2x-----> AC=2*6----> AC=12 ft

the answer is
AC=12 ft
