Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m
Answer:
18/48=20/50 is wrong
Step-by-step explanation:
Because 18/48=37.5% and 20/50=40%
Hope it helps
answer is 2+ 1/4x + 1 the simplest form is x= -3/4 or -0.75
Average rate= change in alt / change in time
r=-378/7=-54ft/min
Answer:
£132
Step-by-step explanation:
15% of 520 is 78
15% of 360 is 54
78 + 54 = 132
