I’m sorry I can’t read that it’s too small..
Answer:
22miles
Step-by-step explanation:
cos is . So, if cos(a)= then use Pythagorean Theorem to determine the length of the "opposite" side.
5² + x² = 13²
25 + x² = 169
x² = 144
x = 12
Now that you know the length of the opposite side, you can plug it in for sin.
sin is . So, sin(a) =
Now, if you switch so you are looking for sin(b), the cos and sin also switch.
cos(b) = sin(a) =
sin(b) = cos(a) =
Answer: sin(b) =
Answer:
Step-by-step explanation:
The surface area of a rectangle can be calculated with:
The surface area of a trapezoid can be calculated with:
Calculate the area of the base, wich is a rectangle:
There are two equal rectangles, therefore, multiply the area of any of them by 2:
Calculate the area of the other rectangle:
There are two equal trapezoids, therefore, multiply the area of any of them by 2:
Therefore, the surface area will be the sum of all the areas calculated:
The answer is 5 * 5. the power or second is how many times you write the number
