HEY YOU, PLS HELP ME!!!! Determine the arc of AB. Give your answer to two decimal places.
1 answer:
<h3>Answer: 19.48</h3>
========================================================
Explanation:
What you type into that calculator (or any calculator really) is this
(124/360)*2*pi*9
This is because we use this generalized formula
L = (x/360)*2*pi*r
where,
- L = arc length, or distance along the piece of the curve
- x = central angle in degrees
- r = radius
So after typing in that expression, you should get roughly 19.47787445 as shown in the screenshot below.
This then rounds to 19.48
Note: I used the calculator's stored version of pi. If you used something like pi = 3.14, then the answer would be slightly different.

Answer:
x=17
Step-by-step explanation:
well the triangles are congruent so that equation has to equal 61, so set it equal to 61, once you do that subtract 10 with 61 giving you 51, then divide 3 with 51 and you get 17
