Agata [3.3K]

Step-by-step explanation:

a) The measure of angle 7 is also 47 degrees. We know this because angle 5 and angle 7 are vertical angles and vertical angles are always equal.

b and c) Since we know that a straight line has an angle of 180 degrees and that the sum of angle 5 and angle 6 will add to this, we can use that to find the value of x like this:

47+2x-5=180\\47-5+2x=180\\42+2x=180\\42-42+2x=180-42\\2x=138\\\frac{2x}{2} =\frac{138}{2} \\x=69

First of all, you must find out how many miles it takes to go 4 hours and 8 hours.

112 ÷ 4 = 28 miles per hour

112 ÷ 8 = 14 miles per hour

So, going downstream will take 28 miles per hour and going in still water will take 14 miles per hour.
