For this case we will define the following:
 A, B: are the values of the triangle angles
 a, b: are the values of the lengths of the sides opposite the angles A, B.
 We then have to use the law of the sine:
 \frac{sinB}{b} = \frac{sinA}{a}
 Clearing the angle B we have:
 sinB = \frac{sinA}{a}*b
 B = arcsin(\frac{sinA}{a}*b)
 Substituting values we have:
 B = arcsin(\frac{sin113}{200}*134)
 B = 38.08
 Answer:
 
the following is true:
 
A. angle B=38.08 degrees

Dyna has ran 3 km of her race. If she is 65% of the way done. how long is the race altogether? Round to the nearest tenth.
Eddi Din [679]

Lets say the race is x km long.

That means she ran 65% of x.

And that also means that 65% of x = 3

So 65%*x=3

65/100x=3

x=3*100/65

x=300/65

x=4.62
