Answer:
The correct option is D.
Step-by-step explanation:
It is given that
![\sin \theta =\frac{-77}{85}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%5Cfrac%7B-77%7D%7B85%7D)
![\cos \theta =\frac{36}{85}](https://tex.z-dn.net/?f=%5Ccos%20%5Ctheta%20%3D%5Cfrac%7B36%7D%7B85%7D)
The angle of terminal ray is θ, it means the angle between x-axis and terminal ray is θ.
![\sin \theta =\frac{perpendicular}{hypotenuse}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%5Cfrac%7Bperpendicular%7D%7Bhypotenuse%7D)
![\cos \theta =\frac{base}{hypotenuse}](https://tex.z-dn.net/?f=%5Ccos%20%5Ctheta%20%3D%5Cfrac%7Bbase%7D%7Bhypotenuse%7D)
Therefore the length of perpendicular is 77 and the base of the triangle is 36.
Since sinθ is negative and cosθ is positive, it means point must be lies on fourth quadrant because in fourth quadrant cosine in positive but sine is negative.
The point of terminal ray is (base, perpendicular) and the sign are used according to the quadrant.
Therefore the point of terminal ray is (36,-77) because in fourth quadrant x is positive but y is negative. Option D is correct.

Answer:
I dont know what you are supposed to answer with but I'll try to help you out. I take it that you have to find the letter ex. the letter <em>d</em> in 1/<em>2d</em> = 7. What you have to do is to get the <em>d</em> by itself and in order to do that you must move the 1/2 over to the 7. So what you would have to do is take the fraction that has the letter on it and move it to the whole number side or the side without the letter but without moving the <em>d</em><em>.</em><em> </em>The <em>d</em> stays on one side while the other numbers are on the other side. When you move the 1/2 over it should look like this sort of due to the limitations of only being able to use text: <em>d</em> = 7 ÷ 1/2. Now after that you have to divide 7 by 1/2 or .5 for question 13 in this instance. Your answer for 13 should be this: <em>d</em><em> </em><em>=</em><em> </em><em>4.5</em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Make</em><em> </em><em>sure</em><em> </em><em>to</em><em> </em><em>show</em><em> </em><em>all</em><em> </em><em>your</em><em> </em><em>work</em><em> </em><em>just</em><em> </em><em>in</em><em> </em><em>case.</em>
13. <em>d</em> = 4.5
14. 18 = <em>f</em>
<em>1</em><em>5</em><em>.</em><em> </em><em>-</em><em>9</em><em> </em>=<em> </em><em>s</em>
<em>1</em><em>6</em><em>.</em><em> </em>-24 = <em>r</em>
17. 0.125 = <em>y</em>
18. -3 = <em>v</em>

Answer:
$(27.75 - 3g)
Step-by-step explanation:
If Grant too $27.75 to the movies last friday
Cost of each movie tickets = $g
Grant bought 3 tickets, so his total cost = $(g+g+g)=$(3g)
The money Grant had leftover = Total Amount Taken to the movie - Total movie cost
=$(27.75 - 3g)
Therefore Grant leftover money after he bought 3 tickets is represented by $(27.75 - 3g) where g is the cost of one movie ticket.
