Answer:

y = 25.20 m

Step-by-step explanation:

By applying tangent rule in ΔABC,

tan(25)° = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{y}{BC}$

BC = $\frac{y}{\text{tan}(25)}$ --------(1)

Now we apply tangent rule in ΔABD,

tan(15)° = $\frac{y}{BC+CD}$

tan(15)° = $\frac{y}{BC+40}$

BC + 40 = $\frac{y}{\text{tan}(15)}$

BC = $\frac{y}{\text{tan}(15)}$ - 40 -------(2)

From equation (1) and (2),

$\frac{y}{\text{tan}(25)}=\frac{y}{\text{tan}(25)}-40$

$\frac{y}{\text{tan}(25)}-\frac{y}{\text{tan}(25)}=-40$

$y[\frac{1}{\text{tan}(25)}-\frac{1}{\text{tan}(25)}]=-40$

y(2.1445 - 3.7321) = -40

1.5876y = 40

y = 25.1953

y ≈ 25.20 m

Therefore, measure of y is 25.20 m.

Find the volume of a prism with triangular bases where the perimeter of the base = 16", apothem = x", and the prism height = 10"

DIA [1.3K]

First, calculate for the area of the base by the equation given,
A = 1/2aP
where A is area, a is apothem, and P is perimeter. Substituting the known values,
A = 1/2(x)(16") = 8x in²
Next, solve for the volume of the prism by the equation,
V = Bh = (8x in²)(10 in)
V = 80x in³
Thus, the volume of the prism is approximately 80x in³.

Find the value of x.

Contact [7]

Answer:

x = 16

Step-by-step explanation:

First, find hypotenuse using 18 and 16.

Using Pythagorean theorem, it gives 24.08

now use it again with the hypotenuse and (36/2) = 18

This gives us x = 16

Solve x2−7x=0 by factoring.

LiRa [457]

X^2 - 7x = 0
Factoring:-
x(x - 7) = 0
x = 0' x - 7 = 0 so x = 7

Solution is 0, 7.
