To solve this, we'll use the trigonometric function called cosine.
The cosine of an angle -in a right triangle-, is equal to the side adjacent to the angle over the hypotenuse of the triangle.
Given the angle 41, its adjacent side is
and the hypotenuse is 55, so:
We solve for
:
The answer is 41.51.
For this case we must solve the following expression:
÷
According to the PEMDAS algebraic order method, we have the following order:
P: Parenthesis
E: Exponents
MD: Multiplication and division
AS: Addition and subtraction
So, we have:
Answer:
-24 is the missing quotient
Answer:
Solution: x ⩾ \frac{8}{5}
Step-by-step explanation:
x 3 + x 2 ≤ 10x – 8
Reorder the terms
3x + 2x ≤ 10x - 8
Collect like terms
5x ≤ 10x - 8
Move the variable to the left
5x -10x ≤ -8
Collect like terms
-5x ≤ - 8
Divide both sides
x ⩾ \frac{8}{5}
