Answer:
1/84
Step-by-step explanation:
multiply 15*4=60 now multiply 30*4=120 and that's your answer hope it helps.
D is the correct answer I think
When you multiply a negative with a positive it’s always a negative
Multiply 5 and -9 to get -45
Answer is -45
This is the application of trigonometry. The distance of the ladder from from the wall will be given by:
cos θ=(adjacent)/(hypotenuse)
θ=72°
adjacent=base (distance the ladder to base of the wall)= xft
hypotenuse=length of the ladder.
Therefore plugging our values in the formula we get:
cos 72=x/15
x=15 cos 72
x=4.635 ft
Hence we conclude that the foot of the ladder is 4.635 ft away from the base of the wall.
