Which expression can be used to find the value of x?

       23 sin 55°

x =           (matches first answer choice)

          sin 85°

Step-by-step explanation:

Note that 2 angles and 1 side length are given.  This is a typical application of the Law of Sines.  The formula for finding the length of side x is:

       23 sin 55°

x =           (matches first answer choice)

          sin 85°

where are the images of the functions i can only see the question you typed.

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
