Is anyone good at geometry if so can you help me please ?
Pachacha [2.7K]

The arcs FA, AB, and <u>BF</u> make up the entire circle, so their measures sum to 360°:

arcFA + arcAB + arcBF = 360°   →   arcBF = 360° - 160° - 140° = 60°

By the inscribed angle theorem, angle BAF has measure equal to half of that of arc BF, so

angleBAF = 30°

By the secant-tangent theorem (not sure if there's an official name for it), the measure of angle ACF is equal to half the difference of the arcs it intercepts, namely BF and FA, so that

angleACF = 1/2 (arcFA - arcBF) = 1/2 (160° - 60°) = 50°

Now use the law of sines for solve for FA:

sin(angleACF) / FA = sin(angleBAF) / FC

sin(50°) / FA = sin(30°) / 10

FA = 10 sin(50°) / sin(30°) ≈ 15.3

How to find area of parallelogram with coordinates of verticles?
ExtremeBDS [4]
You find a parallelogram area by this formula:
A=b\cdot h
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
A(x_1,y_1)\;\;\;\;B(x_2,y_2) \\  \\ &#10;d_{AB}= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} =b

And h is the perpendicular distance between both bases.
You can visit next link to know further about it:
