Answer:

78.3 or 78.29

Step-by-step explanation:

We are asked to find the height of the figure which is the vertical side of the triangle. We are given an angle and we are a side opposite of that angle( the height of the platform) and the hypotenuse 152. So we are going to use sine.

Opposite/Hypotenuse

We use this equation

\sin(theta)  =  \frac{opp}{hypo}

Plug in the values

\sin(31)  =  \frac{x}{152}

Which is about 78.29

12345 [234]

Answer:

The answer is (1/2)z - x - 3y

Step-by-step explanation:

∵ log_{2}P=x

∵ log_{2}Q=y

∵ log_{2}R=z

∵ log_{2}\frac{R^{\frac{1}{2}}}{(P)(Q^{3})}

∴ log_{2}(R)^{\frac{1}{2}}-log_{2}P-log_{2}(Q^{3})

∴ \frac{1}{2}log_{2}R-log_{2}P-3log_{2}Q

∴ \frac{1}{2}z-x-3y
