Answer:
x=40
Step-by-step explanation:
Because every triangle's angles add up to 180 degrees, you know 3x+x+20=180. Since 3x and x are like terms, you can add them to get 4x. 20 and 180 are also like terms. However, to move your 20 to the side of 180, you need to subtract it. So you have 4x=160. To get x by itself, you divide 4x and 160 by 4. 4x/4 is x, and 160/4 is 40. So your answer is x=40.
Since, AB and BC are the same length, the measure of the chord for BC would be 12.5 units
Your answer for this is 86.49
Answer:
You would win the race
Step-by-step explanation:
You would have to swim for 2 minutes and 40 seconds which is the same as 160 seconds.
The opponent would swim
Which is161.5 seconds
This means you would win
Okay to start off the problem you make a fraction of 360/3. you then divide 360 by 3. 360÷3=120. so the rate and unit rate is 120 customers
