Answer: $\frac{2ae^{3}}{3bd}$

Step-by-step explanation:

1. You have the following expression given in the problem above:

$\frac{2ab^{-1}}{3e^{-3}d}$

2. Then, according to the Negative exponent rule, you have that:

$a^{-n}=\frac{1}{a^{n}}$

3. So, based on the rule shown above, the negative exponents indicates that $b$ must be in the denominator and $e^{3}$ must be in the numerator. Therefore, you obtain the following expression:

$\frac{2ae^{3}}{3bd}$

Answer: XVR: 125 ; RVS: 55 ; WVS: 125 ; RST: 110 ; RSV: 70

Step-by-step explanation:

XVR: XVR is equal to WVS (alternate angles), and WVS plus XVW equals 180° (definition of a straight line)

So, 180° - 55° = 125° (this is the measure of SVW, but remember, SVW is equal to XVR)

RVS: RVS is equal to XVW since they're alternate angles, so we know that RVS is equal to 55°

WVS: We already solved this in the beginning

RST: First, we need to find the measure of RSV. To find the measure of RSV, use the fact that a triangle adds up to 180°. We know that the angle RVS equals 55°, and that angle VRS is also equal to 55°. So, we can use this equation:

RSV = 180° - (55° + 55°)

RSV = 70°

Now that we know RSV = 70°, we can find RST

180 - (RSV + RST)

180 - (70° + RST)

RST = 110°

RSV: We already found this

Sorry, that was a lot. Hope it wasn't too confusing.
