Answer:
<u>18°</u>
Step-by-step explanation:
sin 2x=cos zy
m(2x)=72°
cos(π/2-a)=sin a
cos(π/2-72°)=sin72°
cos18°=sin72°
=>m(zy)=18°

Step-by-step explanation:
Joey gives 21 correct answers out of 25 questions on a quiz.
We have to calculate the percent of Joey's correct answer.
Now, percentage of x out of y is given by the simple expression
%.
Hence, the percentage of correct answer given by Joey is given by
%. ( Answer )
No it is not. Anything in the shaded area is a solution m. (4,3) is not in the shaded area so it is not a solution for the graphed inequality.
