Answer: Sin N = \frac{4}{5}

Step-by-step explanation:

Since we have given that

In triangle MPN, ∠P=90°

\cos N=\frac{3}{5}

As we know the formula for "Trigonometric Ratios":

\cos N=\frac{Base}{Hypotenuse}=\frac{3}{5}

By Pythagorus theorem , we get

H^2=B^2+P^2\\\\5^2=3^2+P^2\\\\25=9+P^2\\\\25-9=P^2\\\\16=P^2\\\\P=\sqrt{16}\\\\P=4\ units

So, we get,

\sin N=\frac{Perpendicular}{Hypotenuse}=\frac{4}{5}

Hence, Sin N = \frac{4}{5}

Answer:

b = 37 degrees

Step-by-step explanation:

all of the angles on a triangle added up equal 180 degrees

111 + 32 = 143

180 - 143 = 37

b angle = 37 degrees

The population of turtles is doubling every 3 months. If there are 400 turtles now, how many will there
QveST [7]

First we need to know how many months is 2 years. To answer that we multiply the number of months in a year by 2 and get 48 months.

Every 3 months the population of turtles doubles, but to get how many times the population doubles, you need to divide 48 months by 3 to get 16.

So population of 400 will get <u>doubled</u> 16 times in the following <u>two</u> years.

We construct the following equation where p is the final population,

p=400\cdot2\cdot16=\boxed{12800}

Hope this helps. :)

Freddy drilled into a piece of wood and a joist to attach them. He drilled 4 inches and the wood was 1 1/3 inches thick.
Angelina_Jolie [31]

The depth of the joist that was drilled by Freddy is 5 1/3 inches.

From the information given, we are informed that Freddy drilled into a piece of wood and a joist to attach them and that be drilled 4 inches and the wood was 1 1/3 inches thick.

Therefore, to get the depth that was drilled, we'll need to add the fractions given together. This will be:

= 4 + 1 1/3

= 5 1/3 inches.

Therefore, the depth of the joist that was drilled by Freddy is 5 1/3 inches.
