Answer:
Step-by-step explanation:
There are two ways to do this.
1. You could make an accurate diagram and measure R. This works but the computer won't like it. However you will know if you are correct. An answer ± 2 degrees would tell you that you are likely correct.
2. The second way is to find <C. Similarity guarantees that <C and <R are equal. The adjacent side to angle C is the second longest line. The second longest line in PQR is the adjacent side of <R.
Naturally we will use the second method, but you ought to try the first method. It's cumbersome but it will teach you how to read the values of triangles to make clear the trig functions.
Tan(C) = opposite over adjacent
Tan(C) = 7 / 9
Tan(C) = .77777777...
<C = tan-1(0.7777777...)
<C = 37.87
<C = 37.9
Answer:
P = 31.6
Step-by-step explanation:
distance of AB and CD is 5 units each (used Distance Formula)
distance of BC and AD is units each (used Distance Formula); which is
6
2(6) + 10 = 31.6
Answer:
381.0511777, or 381.051
Step-by-step explanation:
Equation for distance-
B (distance) = A (height) /tan ( e )
B 220 = a/ tan 60
we must rearrange to find height
A=220*tan 60
using our handy dandy scientific calculator on google, we get the following:

divide the volume of jupiter by the volume of earth
1.43*10^15/ 1.09*10^12
1.43/ 1.06 *10^(15-12) divide the number, subtract the exponent
