It is known that ARST - AWXY. If RS =18, ST = 25, and TR=11 then which of the following is closest to the ratio of XY to WX?
(1) 0.44
(3) 2.27
(2) 1.39
(4) 0.72

Step-by-step explanation:

Given

Required

Which is closest to

From the question, we understand that: and are similar.

This means that, the following sides are similar:

So:

This gives:

Express as fraction

--- approximated

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
