The coordinates of point C are (8, 10).
To find the coordinates of C, we use the midpoint formula which states that the midpoint of a line segment is the average of the x-coordinates and the average of the coordinates of y of the endpoints.
Since T(8, 15) is the midpoint of CD and D(8, 20), therefore we can calculate the coordinate of y of C by averaging 15 and 20, which will results in 10.
The coordinates of point C are (8,10). This was determined using the midpoint formula, given that T(8,15) is the midpoint of segment CD where D is (8,20). Both x-coordinates are the same, while the y-coordinate for C was calculated to be 10.

Jawaban:A. setsPenjelasan:Tim itu subjek yang termasuk he, sedangkan kalau he/she/it itu waktu menuliskan verbanya harus disertai s atau es (khusus simple present tense). Karena huruf akhirnya huruf t, maka cukup menggunakan s menjadi kalimat "Tim sets the table."
