Answer:
x=7
Step-by-step explanation:
Since these angles are complementary, they will add up to 90 degrees, so you can set up the equation like so:
8x+5+3x+8=90
First, combine like terms:
(8x+3x)+(5+8)=90
11x+13=90
Then, subtract 13 from both sides:
11x+13(-13)=90(-13)
11x=77
Then divide both sides by 11:
11x(/11)=77(/11)
x=7
7 is your answer

The expression s = 5b represents the Sandra rode her bike and the distance Sandra rode, equals 17 miles.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
Sandra rode her bike 5 times as many miles as Barbara. If b, the distance Barbara rode, equals 3.4 miles.
b = 3.4 miles
Let's suppose the s is the distance Sandra rode then,
s = 5b
The above expression represents the Sandra rode her bike.
Plug b = 3.4 miles
s = 5(3.4) = 17 miles
Thus, the expression s = 5b represents the Sandra rode her bike and the distance Sandra rode, equals 17 miles.
