Answer:
Step-by-step explanation:
Remark
- x is opposite the 90 degree angle. It is the hypotenuse.
- 13 makes up the 57 degree angle. It is the side adjacent.
- The adjacent side and the hypotenuse define the cos(theta).
Formula
cos(theta) = adjacent side / hypotenuse
Givens
Theta = 57 degrees
Hypotenuse = x
Side adjacent = 13
Solution
- Cos(57) = 13 / x Multiply both sides by x
- x*cos(57) = 13 Divide by cos(theta)
- x = 13/cos(57)
- x = 13 / cos(57)
- cos(57) = 0.5446
- x = 13/ 0.5446
- x = 23.87

Answer:
Option B
Step-by-step explanation:
In a triangle , sum of measure of any 2 sides is always greater than the measure of the third side. So
Hence the measure of k is less than 17.
In the triangle , measure of the longest side is 12 cm. As we know that sum of measure of any 2 sides of triangle is greater than the measure of third side , the value of k should be more than 7cm because <u>if the value of k would be 7 , then 5 + 7 = 12 and the sum will get equal to the measure of longest side , hence such triangle wont exist.</u>
Atlast , the range of k is :-
The correct answer would be B. 2/(x + 8)
When you are completing composite functions, you place the entire second function in for x in the first function. Since the letter f comes first in f o g. then we start with the f(x) equation.
f(x) = 2/x
Now since g comes next, we take the entire equation for g(x) and substitute it in.
f o g = 2/(x + 8)
This is answer B.

They ate 0.75. I only wrote it as a decimal.
3÷4= 0.75 Hope it helps :)
Have a good day.
