ABC ,⊿PQR,select an angle ∠ACB =θ
LET θ’s (opp,adj,hypo)=(AB,BC,AC) and (PQ,QR,PR)
Then by similarity,
sinθ=AB/AC=PQ/PR ,cosθ=BC/AC=QR/PR ,tanθ=AB/BC=PQ/QR
the corresponding ratio of (adjacent side/hypotenuse),and hence
the cosine ratio must be the same

Answer:
C. Graph C
General Formulas and Concepts:
<u>Algebra II</u>
Step-by-step explanation:
A cubic function would be f(x) = x³. When we graph this, it should look like Graph C.
Since this is a right triangle, we can use Pythagorean theorem. Pythagorean theorem is a^2 + b^2 = c^2
a = one leg of the triangle
b = the second leg of the triangle
c = the hypotenuse of the triangle
in this problem,
a = 8 in
b = 6 in
c = ?
We need to plug our numbers into the pythagorean theorem and solve for c
8^2 + 6^2 = c^2.
Square each term on the left side.
64 + 36 = c^2
Add the terms together on the left side.
100 = c^2.
Take the square root of each side
10 = c
The missing side is 10 inches
Answer:
2
Step-by-step explanation:
1/6 divided by 1/12
=1/6*12/1
which if you divide 12 by six, equals 2
Step-by-step explanation:
5/2 times x = 1
5/2 * x = 1
5x =2
x = 2/5
x = 0.4
