Answer:
You need four of them in order to construct a square. and rectangle.A circle doesn't have line segments. It is a curve, not made up of straight lines.
Step-by-step explanation:
I'm guessing you mean laps here
Let's find out how many meters are in a kilometer. Kilo is 1000 more than a single unit, so for every kilometer you have 1000 meters.
so divide 1000/6 to find the amount of laps to swim 1 kilometer
166.6667
Answer:
48 degrees
Step-by-step explanation:
<u>1) Solve for x</u>
Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:

Open up the parentheses

Subtract 20 from both sides

Divide both sides by 5

Therefore, x is equal to 14.
<u>2) Determine angle A</u>

Substitute x with 14

Therefore, the measure of angle A in degrees is 48 degrees.
I hope this helps!
by triangle angle addition law
a + b + c = 180
3x +1 + 2x-1 +40 = 180
5x +40 = 180
5x = 180 - 40 = 140
x = 140/5 = 28
so
b = 2x -1 = 2×28-1= 56-1 = 55
