Answer:its 30.5
Step-by-step explanation:
Tan 21 44 = h / 13428.7
h = 13428.7 * tan 21 44
Height = 5353 feet
75/100 is 3/4 in simplest form. To get this, we divide each number by the common multiple of 25, which gives us 3 and 4.
Answer:
what grade is this?
Step-by-step explanation:
Answer:
a =
and b =
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 = 
So: a =
and b =
