Answer:
The center is (5, -2) and the radius is 9/2
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x − 5)^2 + ( y + 2 )^2 = 81/4
(x − 5)^2 + ( y - -2 )^2 = (9/2)^2
The center is (5, -2) and the radius is 9/2
Answer:
b. 30°
Step-by-step explanation:
In quadrilateral OTPR, angles O and P are supplementary.
angle P = 180° -angle O = 180° -150°
angle P = 30° . . . . matches choice B
Answer:
Yes
Step-by-step explanation:
Since the triangles have two congruent angles, the third angle is also congruent.
The sides of one triangle are proportional to the corresponding sides of the other triangle.
Answer:
6.5
Step-by-step explanation:
I'm not sure if its right but:
(2 × x) - 8 = 5
2x = 13
x = 6.5
Answer:
6:5
Step-by-step explanation:
6:5 is already at its simplest form.
You cannot simplify 5 anymore than it is.
But, it can be written as 1.2 in decimal form (rounded to 6 decimal places).
Though, I do not believe that is the answer you are looking for.
