The answer is D.
9/12 = 3/4
16/24 = 2/3
2/3 is not equivalent to 3/4
2 angles opposite from each other are vertical angles.
Vertical angles are equal to each other.
Since Y is opposite the given angle of 163 degrees, Y = 163.
Answer:
Hi there!
Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees.
Answer:
(3, -1)
Step-by-step explanation:
For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA.
sin angle = opposite side / hypotenuse
cosine angle = adjacent side / hypotenuse
tangent angle = opposite side / adjacent side
If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
cos (L) = j/k
