The circle with center (h, k) and radius r has equation
.. (x -h)^2 +(y -k)^2 = r^2
You have
.. h = 2
.. k = 0
.. r = √5
The center is (h, k) = (2, 0).
Answer:
x = 36°n + 7° OR x = 90°n + 37.5° for any integer n
Step-by-step explanation:
Since cos(x) = sin(90°-x), we have
sin(7x-20°) = sin(90°-(3x+40°)) = sin( 50° - 3x )
sin( x ) = sin( y ) implies either:
x = 360° n + y
or
x = 360°n + 180° - y
Generally sin(x) = sin(y) ⇒ x = 180°n + (-1)ⁿ y
First case:
7x - 20° = 360°n + 50° - 3x
10x = 360°n + 70°
x = 36°n + 7°
Second case:
7x - 20° = 360°n + 180° - ( 50°-3x )
7x - 20° = 360°n + 180° - 50° + 3x
7x - 20° = 360°n + 130° + 3x
4x - 20° = 360°n + 130°
4x = 360°n + 150°
x = 90°n + 37.5°
Answer: Hard to say exactly-- 3 dimensions given.
If 3 x 10, 30 square yards. If 10 x 7, 70 square yards. If 7x3, it's 21 square yards.
Step-by-step explanation:
Rectangles have only 2 dimensions: Length and width. Multiply the two numbers to get Area.
I hope this helps you figure it out,no matter what dimensions are given. Remember the Area will be expressed as Square Units.
