Find the cosine of ∠D.

Mathematics

Yuliya22 [10]2 years ago

It should be 5/13 because the opposite angle from D is 12, which you would use if you are looking for sine. But, since you are looking for cosine, it is adjacent over hypotenuse. Therefore leaving you with 5/13, since your hypotenuse is always your longest side and the adjacent is the other side from the one opposite of the angle.

Two angles are supplements if their sum is 180 degrees. The measurement of
Aleksandr-060686 [28]
X represents (smaller) angle 1, y represents (larger) angle 2:

180 = x + y
y = 6x + 5

180 = x + y
180 = x + (6x + 5)
180 = 7x + 5
175 = 7x
25 = x

180 = 25 + y
155 = y

the smaller angle (x) is 25 degrees.

What is the solution to equation. -x+2=3x+2
Mumz [18]

Answer:

x=0

Step-by-step explanation:

x+2=3x+2

Step 1: Subtract 3x from both sides.

x+2−3x=3x+2−3x

−2x+2=2

Step 2: Subtract 2 from both sides.

−2x+2−2=2−2

−2x=0

Step 3: Divide both sides by -2.

−2x

−2

=

0

What is the equation of the quadratic graph with a focus of (5, −1) and a directrix of y = 1?
pav-90 [236]
(x-h)^2=4p(y-k)
vertex is (h,k)
p is the distance from focus to vertex and distance from vertex to directix (vertex is in middle of directix and focus)
if p is positive, the parabola opens up and the focus is above the directix
if p is negative, the parabola opens down and the focus is below the directix
 
we see the directix is over the focus (1>-1) so the parabola opens down and p is negative
distance from (5,-1) to y=1 is 2 units
2/2=1
p=-1 since p is negative
1 up from (5,-1) is (5,0)
veretx is (5,0)
(x-5)^2=4(-1)(y-0)
(x-5)^2=-4y is the equation
