The distance from the lighthouse to the boat will be given by:
tan θ=opposite/adjacent
θ=angle of depression=23
opposite= height of the lighthouse
adjacent=distance from the boat to the bottom of the light house
hence
tan 23=210/a
thus solving for a we obtain:
a=210/tan23
hence
a=494.73 ft
2^(3-9)-11 =
1 step: subtract the 3 and 9 to get 6
(3-9)=6
2 step: multiply 2 to its self 6 times and
you should get 64
2*2=4*2=8*2=16*2=32*2=64
3 step: subtract 11 by 64 to get 53
64-11=53
hope I help if so hit the brainliest thanks
I don’t understand your answerso you can be more specific?
Answer:
65mph
Step-by-step explanation:
Answer:
23 maybe because there is a 90 degree angle
