Answer:
Step-by-step explanation:
<u>Given system:</u>
Eliminate r to solve for s.
<u>To do so, double the first equation and then subtract the second one:</u>
<u>Subtract</u>
- 4s - (-s) = 104 - 4
- 5s = 100
- s = 100/5
- s = 20
Correct choice is (4) 20
Answer:
16x- 20y=20
Step-by-step explanation:
20y-20y =0
so answer is 16x
Answer:
15.78°
Step-by-step explanation:
Let the angle be x.
From the x, the known sides are the opposite side, O(13) and the adjacent side, A(46)
Therefore, The trigonometric ratio is the tangent ratio.
tan x = O/A
tan x =13/46
x = 15.78°
