Geometry - eh?
I think there's something missing here.

Circles with centers (2,1) and (8,9) have radii 1 and 9, respectively. The equation of a common external tangent to the circles can be written in the form y=mx+b with m < 0. What is b? I drew the diagram and the tangents but to no avail. I cannot seem to find the points ...

measured along the diagonals, so diagonal is twice as big

Use Heron's formula. Let a, b and c be the sides of a triangle. Let s = a + b + c Therefore the area of triangle can be calculated using this formula: A = sqrt[ (s)(s-a)(s-b)(s-c) ] It should be a little easy using this formula, so I guess you can do it on your own. :) ...

GEOMETRY CIRCLES PLEASE
This is just too easy. Remember that both tangents to the same circle from an exterior point are equal. so AB = AC but AC is also tangent to the small circle so AC = AD but AD is also a tangent to the circle at the right so AD = AE Since the are all equal , and AB = 15 each ...

math that comes before calculus, usually 2nd year algebra and trigonometry. Geometry comes into play as well.

Height of the kite from the hand =35-3 = 32 ft Distance of the kite from hand = x feet using the formula sin(32) =32/x x = 32/sin(32) =60.3865572736188208=60.4 .............Ans(c)

The diagonals form 2 30o-60o rt. triangles. h = 24*sin30 = 12 In. W = 24*cos30 = 20.8 In. P = 2*(W+h) = 2*(20.8+12) = 65.6 In.
