Step-by-step explanation:
The distance from the surfer to the shoreline will be found as follows:
tan θ= opposite/adjacent
θ=10°
opposite=7ft
adjacent= x ft
substituting the values in our formula and solving for x we get
tan 10=7/x
hence
x=7/tan10
x=39.69897~ 39.7 ft
The surfer is 39.7 ft from the shoreline.
Answer:
Step-by-step explanation:
Tricky. Very neat.
You are missing the minor arcAC and you need it, but don't fret. It can be found.
The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )
The minor arc is the supplement of x.
The minor arc is also equal to the the central angle
So the minor arc is 180 - x
x = 1/2 (235 - (180 - x) ) Remove the inside brackets
x = 1/2 (55 + x ) Remove the remaining brackets
x = 1/2 *55 + 1/2x Subtract 1/2x from both sides
1/2 x = 27.5 Multiply both sides by 2
x = 55
The correct answer is C. t= 8ln(100)
Hope this helped! :)
