Answer:
Step-by-step explanation:
let l be length of string.
Then 70/l=sin 40
l=70/sin 40 ≈108.9 ft
Use subtraction to find the lengths of segments WX and XY.
Point W is on (9,3), point X is on (5,3) and point Y is on (5,9), if I'm reading this correctly.
Point W and point X match with their y-values, so we ignore them. Subtract the x-values, 9 and 5, to get the length. In this case, the length is 4 units.
Point X and point Y match with their x-values, so we ignore them. Subtract the y-values, 3 and 9, to get 6.
Since the problem is asking for length, you always subtract the smaller number from the larger one, as you can't have a negative distance or length.
29. B 500min
30. C 3ft
31. im not sure but i think its A 16
10 more than (+ 10) a number (x) is greater than (>) 50
x + 10 > 50
To solve, subtract 10 from both sides.
x > 40
Hello there!
Here is the answer worked out for you!
12x[-1+sqrt(5)]
-12x+12xsqrt(5)
Remember that you can only add like terms so you can't add -12x to 12xsqrt(5). The radical makes it an unlike term.
I hope this helped and best wishes!
