Answer:
The chair travels approximately 4,394.924 feet.
Step-by-step explanation:
We need to use trigonometric functions to solve this problem. You are given the opposite side of an angle and asked to find the hypotenuse. This means you must use sine, because sine is the ratio between opposite and hypotenuse.
Set up the equation as so:
sin(21) = 1575/x
(x being the hypotenuse). Solve for x by multiplying both sides by x and then dividing both sides by sin(21). Solve 1575/(sin(21)), and you get 4,394.924273, or 4,394.92
Answer:
No
Step-by-step explanation:
I say no because if we were to replace x with 8, the equation should look like this = 8 + 4 = 32. Since this doesn't make sense, 8 cannot be x. X would be 28 which would equal 32 and would be the right answer.
Answer:
Step-by-step explanation:
- 62 = - 15(x - 1) + 4
- 52 = - 15x + 15 + 4
- 52 = - 15x + 19
- 52 - 19 = - 15x + 19 - 19
- 71 = - 15x
- 15x ÷ - 15 = - 71 ÷ - 15
Sum of interior angles of a triangle = 180
so
