tan(angle)= Height/base

tan(59) = height / 63

Height = 63 x tan(59)

Height = 105 feet

We have a right triangle and an indicated angle of 59°. Opposite that angle is the height of the building, which we seek. Adjacent to that angle is the distance to the building, which we know is 63 feet.

We have a problem with opposite and adjacent so we use the tangent function.

tan 59° = h / 63

h = 63 tan 59° ≈ 104.8496074

Answer: 105 feet

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other

Given the functions expressed as:

$h(x) =\sqrt{2x+2}\\g(x)\frac{x^2-2}{2} \\$

In order to check whether they are inverses of each other, we need to show that h(g(x)) = g(h(x))

Get the composite function h(g(x))

$h(g(x))=h(\frac{x^2-2}{2} )\\h(g(x))=\sqrt{2(\frac{x^2-2}{2} )+2}\\h(g(x))=\sqrt{x^2-2+2} \\h(g(x))=\sqrt{x^2}\\h(g(x))=x$

Get the composite function g(h(x))

$g(h(x))=\frac{(\sqrt{2x+2} )^2-2}{2} \\g(h(x))=\frac{2x+2-2}{2}\\g(h(x))=\frac{2x}{2}\\g(h(x))=x$

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other

Help please asap!!<br> A- z=15<br> B- z= 20<br> C- z=23<br> D- z=41

grigory [225]

Answer:

z = 15

Step-by-step explanation:

The sum S of the interior angles of a regular polygon is given by the formula

S = (n-2) x 180 where n is the number sides

Here n = 9

So S = (9-2) x 180 = 7 x 180 = 1,260

There are 9 interior angles and each angle is (5z + 65)

So the sum of all 9 interior angles = 9 (5z + 65)

= 45z + 585

Set these equal to each other and solve for z

45z + 585 = 1260

45z = 675

z = 675/45 = 15

What is the value of x/3y , when x = 18 and y = 3?

tekilochka [14]

So when you work with variables (x, y or any other letter), when they're beside a number it usually means to multiply.

So 3y can also be written as 3(3). So 3 multiplied by 3 is equal to 9

So now our problem looks like this,

x/9.

Since we already know what x is equal to, our problem will look like this

18/9.

So now all we have to do is divide.

18 divided by 9 is 2

So therefore, your answer is 2.

I hope this helps :)
