Answer:
idk
Step-by-step explanation:
Answer:
center = (-2, 3)
radius = 2
Step-by-step explanation:
(x+2)^2 + (y-3)^2 = 4
Use the formula: (x - h)^2 + (y - k)^2 = r^2
where (h, k) = center, radius = r

...
(x - (-2))^2 + (y - 3)^2 = 4 = (2)^2
center = (-2, 3)
radius = 2
The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
Answer:
D. 65°
Step-by-step explanation:
The measure of the angle at crossed chords is the average of the measures of the intercepted arcs:
m∠XYZ = (1/2)(arc XZ +arc WV)
m∠XYZ = (1/2)(86° +44°) = 130°/2
m∠XYZ = 65°
