If the figure is a rhombus, then that means that the place where the two lines intersect is 90°.
The one at the top is 63°. All triangles must equal 180°. So you then add 90 + 63 and get 153. Then subtract that from 180. You get 27.
Y will be 27° too. I'm sorry if this was wrong, but there wasn't very much information in that picture. It didn't even say if it was drawn to scale or not. I think it's right though.

If the center point of rhombus is at a 90 degree angle then the y would be 27 degrees, and the x would probably be 90 degrees if the center is a right angle

The standard form of the equation of a circle is (x−5)2+(y−6)2=1.

Crank

Answer:

(A) $x^2+y^2-10x-12y+60=0$

Step-by-step explanation:

The standard form of the equation of a circle is given as:

$(x-5)^2+(y-6)^2=1$

Simplifying the above given equation, we get

$x^2+25-10x+y^2+36-12y=1$

$x^2+y^2-10x-12y+36+25=1$

$x^2+y^2-10x-12y+61=1$

$x^2+y^2-10x-12y+60=0$

which is the required general form of the equation.

Hence, option A is correct.

The Last on = 45x^2 - 2x - 8

Reason being is because you would group and multiple:
(9x - 4) • (5x +2)

Find all solutions to the equation:

crimeas [40]

Let z = sin(x). This means z^2 = (sin(x))^2 = sin^2(x). This allows us to go from the equation you're given to this equation: 7z^2 - 14z + 2 = -5

That turns into 7z^2 - 14z + 7 = 0 after adding 5 to both sides. Use the quadratic formula to solve for z. The only solution is z = 1 (see attached image). Since we made z = sin(x), this means sin(x) = 1. All solutions to this equation will be in the form x = (pi/2) + 2pi*n, which is the radian form of the solution set. If you need the degree form, then it would be x = 90 + 360*n

The 2pi*n (or 360*n) part ensures we get every angle coterminal to pi/2 radians (90 degrees), which captures the entire solution set.

Note: The variable n can be any integer.
