plugging in the trig values, you have .1051x = .2309(1.1-x) Have you forgotten your algebra I? .1051x = .2540 - .2309x .3360x = .2540 x = 0.756

Hmm. By the time you get to trig, a little algebra I should not throw you. M w cosx = w sinx M = w sinx / w cosx = sinx/cosx = tanx Where did you get stuck on the way?

Come on, guys. By the time you take trig, a little algebra shouldn't be a problem . . . an isosceles triangle has two equal sides. the perimeter is the sum of all the sides 2x+9 + 2x+9 + 3x = 60 7x + 18 = 60 x = 6

3^2 = (5 + 2x)(5 - 2x) = 25 - 4x^2 4x^2 = 16 x^2 = 4 x = 2 or -2 are the two solutions. The product of those two solutions is -4. This is not a trig question. It is about logartithms and algebra.

Trig 30
x/2 = 2pi/3 yields a unique solution of x = 4pi/3 Does this answer come from some trig equation? Your subject title suggests that. In that case find the period of the trig function, then add k(period) to 4pi/3, k an integer.

you want sin(2x) = 1/2 tan(x) 4 sinx cosx = sinx/cosx sinx (4cos^2(x) - 1) = 0 so, sinx = 0 or cosx = 1/2 or cosx = -1/2 sinx = 0 at x = 0 or 180 cosx = 1/2 at x = -60 or 60 cosx = -1/2 at x = 120 why were you desperate? This is just a little algebra and standard trig angles.
