Question

Help please she wants me to show my work

Answer 1

Explanation:

Let us call the missing angle x, then sine of x gives

`\sin x=(51)/(55)`

taking the inverse sine of both sides gives

`x=\sin ^(-1)((51)/(55))`

Using the calculator we evaluate the above to get

`x=68.01`

which rounded to the nearest integer is

`x=68^o`

which is our answer!
