For this case we have that by definition of trigonometric relations of a rectangular triangle that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle.
That is to say:
![Sin (30) = \frac {IR} {14}](https://tex.z-dn.net/?f=Sin%20%2830%29%20%3D%20%5Cfrac%20%7BIR%7D%20%7B14%7D)
We clear the length of the leg:
![IR = 14 * sin (30)\\IR = 14 * \frac {1} {2}\\IR = 7 \ in](https://tex.z-dn.net/?f=IR%20%3D%2014%20%2A%20sin%20%2830%29%5C%5CIR%20%3D%2014%20%2A%20%5Cfrac%20%7B1%7D%20%7B2%7D%5C%5CIR%20%3D%207%20%5C%20in)
Answer:
![IR = 7 \ in](https://tex.z-dn.net/?f=IR%20%3D%207%20%5C%20in)
Answer:
d
Step-by-step explanation:
You can tell if the equation is linear or not if the equation makes a straight line on a graph.
79+43=122
122+58=180
so the answer is A 58
First do 4.04 mil - 3.66 mil to get .38 mil (which is 380 thousand) then divide 380,000/10 to get answer J. 38,000. Hope this helped
