((-3,-4) i have to type this cuz it’s literally 30 characters
Cos theta = 1 /sec theta so cos theta = 1/2
and 4 cos theta = 4 * 1/2 = 2
sin theta = sqrt ( 1 - cos^2 theta) = sqrt 1 - 1/4) = sqrt (3/4) = sqrt3/2
root 3 sin theta = 3/2
tan theta = sin theta / cos theta = sqrt3 / 2 / 1/2 = 2*sqrt3/ 2 = sqrt3
so the answer is 2 - 3/2 / sqrt3 = 1/2 / sqrt3 = sqrt3 / 6
Answer:
x=h/4−3y−1/2
Step-by-step explanation:
h=4(x+3y)+2
1) <u>Distribute</u> the 4 to x and 3y:
h=4x+12y+2
2) Subtract a 12y and a 2 from both sides:
4x=h-12y-2
3) Divide everything by 4:
x=h/4-3y-2/4
4) Simplify -2/4 to -1/2:
x=h/4−3y−1/2
