An expression is just a mathematical phrase. A numericalexpression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables!
Hope this helped :)
Answer:
sin = opp / hyp
cos = Adj / hyp
tan = opp / adj
7. cos 41 = x / 86
8. sin x = 5/13
9. cos x = 9/37
10. tan 61 = x/28
11. sin 41 = x/65
12. tan x = 79/84

Step-by-step explanation:
<u>The circle has a circumference:</u>
This the is arc of full length θ = 360°
<u>Each degree of arc length is:</u>
- s = 2πr*θ / 360 = πrθ / 180
<u>We have:</u>
<u>The arc length is:</u>
- s = π*6*25/180 = (5/6)π inches terms of π
<u>The same arc is:</u>
- s = (5/6)*3.14 = 2.62 inches (rounded)
