Your picture is a bit blurry. What is the equation on WX and on ZY?
Answer:
The answer is C.
Step-by-step explanation:
Hit 'em with the Law of Sines.
sin(A)/a = sin(B)/b.
Let's say x is equal to "A", thus 5 is "a".
sin(x)/5 = sin(B)/b.
We could go for the obvious choice for "B", which would be the 90 degrees shown. To solve for the hypotenuse which will be "b", let's use the Pythagorean Theorem:
a^2 + b^2 = c^2
5^2 + 20^2 = c^2
25 + 400 = 425
sqrt(425) = about 20.6, which we can now substitute "b" with.
sin(x)/5 = sin(90)/20.6
sin(x)/5 = 1/20.6
sin(x)/5 = 0.04854...
sin(x) = 0.2427...
You can plug in sin^-1(0.2427) into your calculator, and you should end up with something like 14.047... which equates to answer choice C.
Answer:

Step-by-step explanation:
The given interval : x = 0 to x = 10
Length of interval = 10 - 0
= 10

⇒ Number of equal intervals = 5

Answer
0.00145
Step-by-step explanation:
(5 x 10^-4) + (9.5 x 10^-4)
0.0005 + 0.00095
= 0.00145
