Given the following triangle, what is the measure of the missing side?

Karolina [17]

It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6

Find cot theta if 180° < theta < 270° and cos theta = - sqrt 3/2

avanturin [10]

Answer:

cot theta = -√3

Step-by-step explanation:

we are given that cos theta = - √3/2 within the range 180° < theta < 270° and

since cos theta = adj/hyp

adj = - √3

hyp = 2

Get the opposite using the pythagoras theorem

hyp^2 = opp^2 + adj^2

2² = opp² + (-√3)²

4 = opp² + 3

opp² = 4-3

opp² = 1

opp = 1

tan theta = opp/adj

tan theta = - 1/√3

Recall that cot theta = 1/tan theta

cot theta = 1/(-1/√3)

cot theta = -√3

A cylindrical can of baked beans has a diameter of 8 cm and a height of 9 cm.

strojnjashka [21]

Formula for volue of cylinder is area time height. Lets find area
A= $\pi r^2$
diameter=2r
8=2r
r=4
Now substitute r to $A= \pi r^2$
A= $\pi 4^2= 16\pi$
Now we have formula
V= $16 \pi *height=16 \pi *9=144 \pi$ - its the result, so B
