Given right triangle ABC. To the nearest degree, find the measure of angle B.

DedPeter [7]

Answer:

Step-by-step explanation:

We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.

sin(B) = side opposite / hypotenuse:

$sin(B)= \frac{ 4.8}{ 5.1}$ so

sin(B) = .9411764706

Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:

$sin^{-1 ($

Enter that decimal after the open parenthesis and hit "enter" to get

B = 70.25 or 70°

lucas lives 5/8 mile from school.kenny lives twice as far as lucas from school.how many miles does kenny live from school

dexar [7]

1. Lucas Lives 5/8 miles from their schools
=> 5/8 miles is equals to:
=> 5 / 8 = 0.625 miles.
Now, the problem says that Kenny lives twice as far as Lucas from their school.
Therefore, we only need to multiply the total number of miles of Lucas distance from house to school to be able to get what is the distance of Kenny’s house to school
=> 0.625 * 2 = 1.25 miles or 1 and ¼ miles.
