Answer:
x =53.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side/ adjacent side
tan x = 28 /21
Take the inverse tan of each side
tan ^-1 (tan x) = tan ^-1 (28/21)
x = 53.13010235
Rounding to the nearest tenth
x =53.1
Answer:
9.5 feet
Step-by-step explanation:
So let's review the equations we need to know.
Circumference= π x d or π x 2r
Since we are solving for r, let's stick with the 2nd one.
Next, plug in the values.
59.66=3.14 x 2r
simplify.
59.66=6.28r
9.5=r
done!
the radius is 9.5 feet!
Answer:
I need more information
Step-by-step explanation:
280 miles - is that the round trip or one way?
280 one way
boat velocity = 30 mph
current velocity = 10 mph
280 (140 one way)
boat velocity = 15 mph
current velocity = 5 mph
