Find the sine, cosine, and tangent of 45 degrees.

Mathematics
1 answer:
frosja888 [35]3 years ago
4 0

Answer:

The correct answer is option C.

Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1

Step-by-step explanation:

The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.

The table is easily available on the internet.

WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.

The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.

So

Sin 45 = √2/2

Cos 45 = √2/2

and

Tan 45 = 1

So the correct option is C.

Step-by-step explanation:

f(x)=(x-4)(x+2)

f(x)=0=y

0=(x-4)(x+2)

Which is the fractional portion of the solution to 5 3/8 + 2 3/12
Virty [35]


First we need to find the common denominator for 8 and 12.

8 = 8, 16, 24

12 = 12, 24

So we have 24 as our common denominator.

5 3/8 =   5  9/24

<u>2 3/12 = 3  6/24</u>   now we can add.

              8   15/24

So that would be your answer 8 15/24

Hope this helps you. :-)
