B=h+4, m=h-2 now we are told

b+h+m=11, using b and m found above in this equation gives us:

h+4+h+h-2=11

3h+2=11

3h=9

h=3 and since b=h+4, m=h-2

historical=3, biography=7, mystery=1

h-------> the number of hours Noelle runs for the rest of the month

we know that

The inequality that represent the situation is

$10+5h>50$

Solve for h

Find c, the hypotenuse, rounded to four decimal places, in a right triangle with b = 16 and B = 55

Fudgin [204]

Answer:

c=19.5324

Step-by-step explanation:

In given triangle ABC, we have been give values of angle B=55 degree, angle C is right angle and b=16.

Now using those values, we need to find the value of side b.

apply formula of sin

$\sin\left(B\right)=\frac{AC}{AB}$

$\sin\left(55\right)=\frac{16}{c}$

$0.819152=\frac{16}{c}$

$0.819152c=16$

$c=\frac{16}{0.819152}$

$c=19.5323944762$

Hence final answer rounded to four decimal places is c=19.5324
