an Olympic swimming pool is 6 meters long how many lives will and have to swim in order to swim 1 kilometer
vlada-n [284]
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

Will give brainlliest :>
Goshia [24]

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:

A+B=90\\(2x+20)+(3x)=90

Open up the parentheses

2x+20+3x=90\\5x+20=90

Subtract 20 from both sides

5x+20-20=90-20\\5x=70

Divide both sides by 5

\frac{5x}{5} =\frac{70}{5} \\x=14

Therefore, x is equal to 14.

<u>2) Determine angle A</u>

A=2x+20

Substitute x with 14

A=2(14)+20\\A=28+20\\A=48

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
