Given that sin(x)=7/11, find cos(90-x). a. 4/11 b. 7/11 c. 11/7 d. 11/4

Based on the given equation above, get the value of x first so that this value can be substituted to the second equation. Value of x can be obtained by taking the arc sin of 7/11 which gives an answer of 39.52 degrees. Substituting this value to the second equation cos (90-39.52) gives an answer equals to 7/11

I’m vary good with science if you need with that
