What are the equations & answer to these 2 problems ?

mrs_skeptik [129]

Remark

First of all, we had best correct the labeling. The adjacent is the side making up the unknown angle, and the opposite is the side not making up the given angle (in this case, x)

So you have mixed up the opposite and the adjacent. You need to switch them.

Step Two (Bottom Diagram)

Sin(x) = opposite / hypotenuse

Sin(x) = 12 / 18

Sin(x) = 2/3

Sin(x) = 0.6666666666

x = sin-1(0.66666666)

x = 41.18103

Problem One (Top One)

Sin(x) = opp/hypotenuse

Sin(x) = 4/5

Sin(x) = 0.8

x = sin-1(0.8)

x = 53.13 Answer <<<<<

Fred and Ben each ran laps around the track. Fred completed his run in 16 minutes. Ben completed his run in 3/4 of the amount of

m_a_m_a [10]

Answer:

Time required by Ben was 12 minutes.

Step-by-step explanation:

Given:

Time Required for Fred = 16 mins

Ben completed his run in 3/4 of the amount of time of Freds run.

We need to find the time required by Ben.

Now Given that;

Ben completed his run in 3/4 of the amount of time of Freds run.

It means that time required by Ben is equal to 3/4 times time required by Fred.

Time required by Ben = $\frac{3}{4}\times Freds \ run$

Time required by Ben = $\frac{3}{4}\times 16 = 12\ mins$

Hence Time required by Ben was 12 minutes.
