Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = ![\frac{opposite}{adjacent}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Badjacent%7D)
finding d:
⇒tan 63 = ![\frac{d}{3.1}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7B3.1%7D)
tan of 63 is 1.963
⇒ 1.963 = ![\frac{d}{3.1}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7B3.1%7D)
multiply 3.1 on both sides
⇒ 1.963 x 3.1 =
x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 = ![\frac{7}{n}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bn%7D)
tan of 45 is 1
⇒ 1 = ![\frac{7}{n}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bn%7D)
multiply 7 on both sides:
⇒ 1 x 7 =
x 7
7 = n
The answer is D. 4x7+5=33 8x7+5=61. Hope it helps
12 use a calculator i did it
Answer is C because they are next to each other in 180 degree angles or 90 degrees angles
