Answer:
First notice that θ is in quadrant I, where the sine and tangent will also be positive.
Then draw the angle in quadrant I. Drop a perpendicular to the x axis.
Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.
Then sinθ=vertical/hypotenuse= 24/25 and tanθ= vertical/horizontal= 24/7

Answer:
5.0 x 10^-2
Step-by-step explanation:
you need to move the decimal place to the right in order to be 1 or over.
moving the decimal to the right will cause the exponent to be negative. opposite direction is positive.
the equation would be x-12=20.
the solution would be x=8.
10 students would have pets because 10/18 is simplified to 5/9 I think
