#4) From the reference angle of 58° we can see that we have the side opposite to that angle as well as the hypotenuse. Recall that sin=opp/hyp so we are going to use sine to find that side
sin(58°) = \frac{x}{19}        (multiply both sides by 19 to isolate x)
19 sin(58°) = x      (plug into calculator)
16.1 = x
#5) From the reference angle of 56°, we see that we have the adjacent and the opposite sides. Remember that tan=opp/adj so we will use tangent to find x
tan(56°) = \frac{12}{x}        (multiply both sides by \frac{1}{12})
\frac{tan(56)}{12} =  \frac{1}{x}          (flip them so x is on the top)
[tex] \frac{12}{tan(56)} = x
8.1 = x

What you have presented is called a cyclic quadrilateral. A cyclic quadrilateral is a 4 sided figure whose angles (4 of them) all touch the circumference of a circle.

Here's what you want to know. Two angles that are opposite each other are supplementary (they add to 180 degrees)

Equation
x + 80 = 180 Subtract 80 from both sides.

Solution
x + 80 - 80 = 180 - 80 Combine
x = 100

Answer
x = 100

A boat traveled 280 miles downstream and back. The trip downstream took 7 hours. The trip back took 14 hours. Find the speed of
Brrunno [24]
Let, the speed of boat = x 
Speed of current = y
So, x + y = 280/7
x + y = 40   ---- first equation

x - y = 280/14 
x - y = 20  
x = 20 + y

Substitute this value of x in first equation, 
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10

Substitute this in first equation, 
x + 10 = 40
x = 30

In short, Speed of Boat = 30 mph, & speed of current = 10 mph

Hope this helps!
