Using th epythagorean theorem.
52^2-48^2= x^2
2704-2304= x^2
400=x^2
x=20
Final answer: D
Answer:
∠y = 62.5°
∠x = 27.5°
Step-by-step explanation:
z is right angle. ∠z = 90°
∠x = ∠y - 35
∠x + ∠y + ∠z = 180 {Angle sum property of triangle}
y - 35 + y + 90 = 180
y + y - 35 + 90 = 180 {Combine like terms}
2y + 55 = 180
2y = 180 -55 {Subtract 55 from both sides}
2y = 125 {Divide both sides by 2}
y = 125 /2
∠y = 62.5°
∠x = 62.5 - 35 = 27.5°
The answer is C
The answer is C because the function form for a linear function is f(x) = ax+b and the answer C has x which is the slope and -3 which would represent the y-intercept also known as b
Answer:
center = (3, 0)
radius = 2
Step-by-step explanation:
Standard equation of a circle: ![\sf (x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%5Csf%20%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(where (h, k) is the center of the circle and r is the radius)
Given equation:
![\sf (x-3)^2+y^2=4](https://tex.z-dn.net/?f=%5Csf%20%28x-3%29%5E2%2By%5E2%3D4)
Rewrite in standard form:
![\sf \implies (x-3)^2+(y-0)^2=2^2](https://tex.z-dn.net/?f=%5Csf%20%5Cimplies%20%28x-3%29%5E2%2B%28y-0%29%5E2%3D2%5E2)
Therefore
- center = (3, 0)
- radius = 2
