Solve for y. will give brainiest

hoa [83]

Answer:

y = 81°

Step-by-step explanation:

let the 5 th angle in the pentagon be x

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, then

sum = 180° × 3 = 540°

sum the angles and equate to 540

x + 95 + 125 + 116 + 105 = 540

x + 441 = 540 ( subtract 441 from 540 )

x = 99°

x and y are adjacent angles and supplementary, sum to 180° , that is

x + y = 180°

99° + y = 180° ( subtract 99° from both sides )

y = 81°

$ 20,000 is invested at a rate of 5% compounded quarterly. Identify the compound interest function ta model the situation. Then

liq [111]

Answer:

the balance after 5 years is: 26540.744

Step-by-step explanation:

Given the information:

P = initial balance = $ 20,000
r = interest rate (decimal) = 5% = 0.05
n = number of times compounded annually = 4
t = time = 5

We have the compound interest function ta model the situation is:

$A=P(1+\frac{r}{n} )^{nt}$

<=> A = $20000(1+\frac{0.05}{4} )^{4*5}$

<=> A = $26540.744

Hence, the balance after 5 years is: $26540.744

Paul wrote the equation t=2m+40 to represent the temperature, t, in degrees Celsius, after a substance had been heated for m min

Usimov [2.4K]

First you need to fill in the variables with what you already know, so
t=2m+40.
You don’t have enough information to solve this problem. You need to have only 1 variable to solve it or you need more information

The length of a shadow of a tree is 150 feet when the angle of elevation of the sun is 39°. Approximate the height of the tree.

Answer:

The height of tree is approximately 121.5 feet.

Step-by-step explanation:

We are given following in question:

Length of shadow = 150 feet

Angle of elevation of the sun =

$\theta = 39^\circ$

The tree and the shadow forms a right angled triangle.

Thus, with the help of trigonometric relation, we can write:

$\tan \theta = \dfrac{\text{Height of tree}}{\text{Length of shadow}}$

Let x feet be the height of tree.

Putting all the values, we get,

$\tan 39^\circ = \dfrac{x}{150}\\\\0.80978 = \dfrac{x}{150}\\\\\Rightarrow x = 150\times 0.80978\\\Rightarrow x = 121.467 \approx 121.5$

Thus, the height of tree is approximately 121.5 feet.
