Answer:
a) 52.5 ft. b)40.1ft c)12.5ft d) 72.6
Step-by-step explanation:
a) The height of the lighthouse is 84ft, and the angle of elevation is 58 degrees.
tan58=84/x
find x by dividing 84 by tan58, and you get 52.5ft.
b) do the same thing, except 131 is in the base of the right triangle shape. That being said, do tan17=x/131.
multiply 131 by tan17, and you get x=40.1 feet.
c) This question wants you to find the length of the slide, (basically the hypotenuse).
given the angle to be 46, do sin46=9/x
since sin is opp/hyp
9/sin46= 12.5ft
d) Find the angle of elevation by using inverse tan given the base to be 5, and the height to be 16ft.
tan^-1=(16/5)=theta
x=72.6 hope this helps!
( 0, 8 ) → B
Apply the given rule to the coordinates of point B (2, 5 )
thus B' = ( 2 - 2, 5 + 3 ) = (0, 8 )
Answer:
B
Step-by-step explanation:
3(6)-5(-3)≥10
18-(-15)≥10
18+15≥10
33≥10
Answer:
the answer is 3: 26x-19
Step-by-step explanation:
f(x)=4x-5 g(x)=6x-3
2f(x)+3g(x)
=2*(4x-5)+3*(6x-3)
=8x-10+18x-9
26x-19
