Step-by-step explanation:
I think this is correct, tell me if it's not
Answer:
x-2 and x-3 is the answer.
The standard form of hyperbola is:
(x-h)²/a²-(y-k)²/b²=1
center:(4,5)
Length of the horizontal transverse axis: 8-5=3=2a
thus
a=3/2
a²=9/4
b=2
b²=4
Hence the equation will be:
(x-4)²/(9/4)-(y-5)²/4=1
simplifying this we get:
[4(x-4)²]/9-(y-5)²/4=1
A key word to remember when doing this type of math is "SOHCAHTOA".
Sine =
Opposite over
Hypotenuse
Cosine =
Adjacent over
Hypotenuse
Tangent =
Opposite over
Adjacent
Since this is a 3, 4, 5 triangle, with the sides just multiplied by 7, the opposite of A which is 28 would be simplified to 4.
And the Hypotenuse would be simplified to 5.
So, the answer is 4 / 5!
21. D. is the answer. Angle Q is 75 degrees. X=30. The triangle is an isosceles angle so therefore there are 2 angles are congruent to each other, Angle R and Angle Q. All three of the angles should add to 180 degrees.
