Sinθ=opposite side/hypotenuse
cosθ=adjacent side/hypotenuse
where both the sides are relative to theta.
in this case, 22 is your hypotenuse. theta (θ) is the angle you are examining. i've included a diagram for reference because the equations may format differently depending on which angle you choose as theta.
using my diagram:
sinθ = o/h
sin 15 = o/22
sin 15(22) = o
o=5.69m/s
therefore the vertical component is about 5.69m/s.
cosθ=a/h
cos15 = a/22
cos15(22) = a
a = 21.25m/s
therefore, your horizontal component is about 21.25m/s.
Answer:
The area of the triangle is
Step-by-step explanation:
Let
A(0, −2),B (0, −3) and C(8, -3)
Plot the vertices
see the attached figure
Triangle ABC is a righ triangle
The area of the triangle ABC is equal to
substitute
Answer:
b = -1
Step-by-step explanation:
Solve for b means, write in the form of b =...
Given
+ b = - 1 and this is the same as b = - 1.
That is because the plus sign has no real meaning here, so you can ignore it as if it was not there at all.
It so turns out you now have the answer!
The value of the digit 8 is 8,000. To find the answer all you have to do is replace all the other numbers with zero. So 28,175 would be 08,000; and because a zero before a number doesn't mean anything, you end up with just 8,000.
