**Trig**

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?

**trig**

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

**trig**

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.

**algebra 2 and trig (math)**

tan is a trig operator, it needs an operand. You probably mean something like tan^2 Ø - tanØ = 0 factor it tanØ(tanØ - 1) = 0 so tanØ=0 or tanØ=1 Ø = 0 or Ø = π/4 or Ø = 5π/4 since it asked for the positive acute angle Ø = π/4 radians or 45°

**Algebra 2 to Reiny**

you are correct. You can test whether two trig expressions are equal by taking a non-standard angle, like 37°, and evaluating each expression If the question was to "simplify", I would consider the original expression simplified enough. Because of the many trig identities and ...

Subtract 2 pi from 7pi/3. The trig functions of 7 pi/3 will be the same values as the trig functions of pi/3, which is 60 degrees. The cosine of pi/3 is 1/2. That makes the secant 3. The tangent is sqrt3 You should be able to look up or figure out the other funtions of that ...
