Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = 
finding d:
⇒tan 63 = 
tan of 63 is 1.963
⇒ 1.963 = 
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 = 
tan of 45 is 1
⇒ 1 = 
multiply 7 on both sides:
⇒ 1 x 7 =
x 7
7 = n
Answer:
24
Step-by-step explanation:
Split the shape into 2 so you get a triangle and a rectangle.
Find area of triangle:
1/2 x a x b = 1/2 x 3 x 4
= 6 square feet
Find area of rectangle:
b x h = 6 x 3
= 18
Add both together
18 + 6 = 24
Answer:
2.48×10^13 miles
Step-by-step explanation:
There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...
(4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)
= 4.22×3×3.15576/1.609344×10^(8+7-3) mi
≈ 24.8×10^12 mi
4.22 light years is about 2.48×10^13 miles
