Answer:
Step-by-step explanation:
Use <u>tigonometry</u> to find the value of d
- sine = opposite side / hypotenuse
- 306/d = sin 38°
- d =306/sin 38°
- d = 497 m (rounded)
Answer: I would want to mathematically get better at percentages.
Step-by-step explanation:
He got 30 right
(40 x 75)/100
= 3000/100
= 30
Answer:
See below in bold.
Step-by-step explanation:
(1) cosec ( x + 10) = 3
Now cosec x = 1/sin x so
1 / sin (x + 10) = 3
3 sin (x + 10) = 1
sin (x + 10) = 1/3
x + 10 = 19.47 , 160.53 degrees
x = 9.47, 150.53 degrees.
(ii) cot (x - 30) =0.45
cot (x - 30)= 1 /tan (x- 30) so we have
tan (x - 30) = 1 / 0.45 = 2.2222
x - 30 = 65.77 degrees
x = 95.77 degrees.
Answer:
t represents the number of hours.
Step-by-step explanation:
I could be wrong because there is no t in that equation, but the equation should be 9t=26. T would represent the time (in hours)g it would take to go 26 miles.
