Answer:
21 Students played string instruments
Step-by-step explanation:
58 - 16 = 42, 42 ÷ 2 = 21 so 21 + 21 + 16 = 58. because there are sixteen more wind instruments that means you need to have the wind and string equal and then add 16 more winds which is what i did, if you have 21 string instruments and (21+16) 37 wind instruments then you have 58

Answer:
The value of y is 4 cm.
Step-by-step explanation:
First find the lengths of each side (square root of 256 is 16, so each side of the bigger square is 16 cm) of each square (square root of 64 is 8, so each side of the smaller square is 8 cm). Then, since each y value is the same and equal, 16 (length of one side of bigger square) minus 8 (length of one side of smaller square), divided by 2 (because there are 2 y values per length), you get 4 cm. Hope that helps!
a) Due to you have a right triangle, in order to calculate the value of d, use the Pythagorean thorem:
Hence, the distance d is approximately 63.2m
b) To find the angle of elevation, use the sine function of θ, as follow:
Hence, the angle of elevation is approximately 19.8°
