If cos theta = 1/4, then what is the positive value of tan 1/2 theta, in simplest radical form with a rational denominator?

answer: 1 + 1 = 11

step-by-step explanation:

triangle and cube

step-by-step explanation:

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
