Given that the slide is 4.3 m long and makes an angle of 31°, then to get how high the slide is above the ground we use trigonometry formula.
sin θ=opposite/hypotenuse
opposite=x=how high the slide is above the ground
hypotenuse=length of the slide=4.3 m
θ=31°
plugging the values in the formula and solving for x we obtain
sin 31=x/4.3
x=4.3×tan 31
x=4.3(0.6009)
x=2.58387
x~2.6 m
Hence we conclude that the top of the slide is approximately 2.6 m from the ground

Answer:
B
Step-by-step explanation:
rise over run the y-intercept is 3 and you go down 4 and run 3
The first row has 20 + 0 seats, the 2nd row, 20 + 1, 3rd row 20 + 2 . . . until 60th row has 20 + 59 (not 60 as the first row had 0 added on.
therefore you need to add up 20 + 21 + 22 . . . all the way to 76, 77, 78, 79.
79+ 21 = 100, 78 + 22 = 100, 77+ 23 = 100, in fact up to 49 + 51 = 100
That gives us 39 x 100 and add on the the other rows + 20 + 50
= 3970 seats
