Answer:
It's positive when you have 6^-2 it's the same as having 
. So 6^-2 it's 1/36.
Step-by-step explanation:
Let the first angle be A and the second be B.
Complementary angles add up to 90° so:
A + B = 90
We are also told:
A = 6 + 3B; substituting this into the first equation:
6 + 3B + B = 90
B = 21°
A = 6 + 3(21)
A = 69°
Answer:
The missing side has a length equal to 
Step-by-step explanation:
We need to find the length of the missing side on the right triangle. We were given the length of the hypotenuse, and the opposite cathetus, therefore we can use the sine relation. This is done below:
While setting up a fireworks
display, you have a tool at the top of the
building and need to drop it
to a coworker below. Given the equation:
h(t) = -16t^2 + h0
h = 84 feet
it will take the tool to fall
to the ground 2.29 time unit
-84 = -16t^2 – 0
<span>t = 2.29 time unit</span>
