Answer:
The central angle of the arc is 288 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A circle has a circumference of 8. It has an arc of length 32/5 . What is the central angle of the arc,in the degrees?
we know that
The circumference of the circle subtend a central angle of 360 degrees
so
uing a proportion
Find out the central angle for an arc of length 32/5
Answer:
3a) 5/45 you divide by 5
3b) 6/7 you divide by 2
3c) 2/7 you divide by 9
3d) 2/5 you divide by 9
4a) 6
4b) 1 <u>1/4</u> or 5/4 (both are correct)
4c) 3 <u>1/2</u> or 3 <u>3/6</u> (both are correct)
4d) 5 <u>1/8</u>
The fraction bar tells you to divide the top number by the bottom number.
Step-by-step explanation:
For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.
For 4a through 4b, devide the top the bottom number
The vertex angle bisector divides the triangle into two congruent right triangles. The sine of half of the vertex angle will be half of the base divided by the side (from the definition of the sine of an angle). Then the total vertex angle is ...
α = 2×arcsin(3.5/5) ≈ 88.9°
_____
Using the Law of Cosines, the vertex angle can be found as
arccos((7^2 -5^2 -5^2)/(-2*5*5)) = arccos(1/50) ≈ 88.9°
If you put $500 in a bank with a 6% investment rate (which is rather high honestly) then next year you would have $530 in the bank, then 561.80 and so on. I feel like I misunderstood the question, but hopefully this helps, if at all.
May I have brainliest please? :)
