Answer : 2√3
<u>Given </u><u>:</u><u>-</u>
- A equilateral triangle with side length 4.
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The value of x in the given figure.
As we know that in a equilateral triangle , perpendicular bisector , angle bisector and median coincide with each other .
- So the perpendicular drawn in the figure will bisect the given side .
- Therefore the value of each half will be 4/2 = 2 .
Now we may use Pythagoras theorem as ,
→ AB² = BC² + AC²
→ 4² = 2² + x²
→ 16 = 4 + x²
→ x² = 16-4
→ x² = 12
→ x =√12 = √{ 3 * 2²}
→ x = 2√3
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>2</u><u>√</u><u>3</u><u> </u><u>.</u>
I hope this helps.

Answer:
The answer is below
Step-by-step explanation:
The minimum payment on a credit card is based on the total amount owed. A credit card company uses the following rules: For a bill less than $20 the entire amount is due, for a bill of at least $20 but less than $500, the minimum due is $20. For a bill of at least $500 but less than $1000 the minimum due is $40 and for a bill of at least $1000 but less than $1500 the minimum due is $80 dollars. For a bill of $1500 or more the minimum due is 1/10th of the bill.
a. Write a function to describe the minimum payment due.
b. What is the minimum payment due if the bill is $345?
c. What is the minimum payment due if the bill is $1410?
d. What is the minimum payment due if the bill is $1700?
Solution:
Let B represent the minimum due payment for a bill in dollars and let x represent the bill in dollars. Therefore:
For x < 20, B = x
For 20 ≤ x < 500, B = 20
For 500 ≤ x < 1000, B = 40
For 1000 ≤ x < 1500, B = 80
For x ≥ 1500, B = (1/10)x
a)
b) For 20 ≤ x < 500, B = 20
Therefore if the bill is $345 (x = 345), the minimum payment due would be $20
c) For 1000 ≤ x < 1500, B = 80
Therefore if the bill is $1410 (x = 1410), the minimum payment due would be $80
d) For x ≥ 1500, B = (1/10)x
Therefore if the bill is $1700 (x = 1700), the minimum payment due would be $170 (1/10 * 1700)
