In any angle ABC prove tht the perimeter = a/Sin A(Sin A + Sin B + Sin C) Start with perimeter = a+b+c but b= aSinB/sinA and c= aSinC/SinA and if you dont remember, a=a=a*SinA/ SinA
if A+B+C=180degrees, prove that 2sin(B+C)sinA=1-cos2A
in triangle abc ad is bisector of angle a and angle b is twice of angle c prove that angle bac is equal to 72
(a) sinA (b)sinB (c)sinC (d)cosC (e) -sin(A+B)
I don't know the physics behind Snell's Law, but I can do the math Snell's Law says sin(angle of incidence)/sin(angle of reflection) = refractive index since you know the two angles... sin45/sin27 = refractive index =1.5575365 so for an angle of refection of 25º sin(incidence angle)/sin25º=1.5575.. sin(incidence angle)=sin25(1.55..) =.6582433 so angle of incidence = arcsin(.658..) =41.166º That's just the application of Snell's, that part I've done. What I need is: sin(a)/sin(a-25) = RII would solve it by iteration. There is...
(Using ABC, find the following: a) The length of side AC b) The perimeter of ABC c) The area of ABC c=90' AB= 13 in. CB= 12 in.
Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Use the Pythagorean theorem to find the unknown side length. Then find the values of the six trigonometric functions for angle B. Rationalize the denominators when applicable. с a=2, c = 4 b The unknown side length bis (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.) sin B= (Simplify your answer, including any radicals. Use...
