12*2=24
24*3=72
72*4=288
n*(x+1)
288*(4+1)
288*5=1440
Answer:
44 feet
If it takes the horse 44 feet per second, and it takes the cheetah 88 feet, the difference is 44.
So, the horse must be 44 feet ahead to be safe. Hope it helps!
Yes
Reason - figure b has been increased by 3 (x3 for each side)
Eg. figure b - 1. Figure a - 3
Answer:
19.5 miles
Step-by-step explanation:
The question is represented in the image attached.
∠A = 45°, ∠B = 45° + (216° - 180°) = 81°
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
45° + 81° + ∠C = 180°
126 + ∠C = 180
∠C = 180 - 126
∠C = 54°
The sine rule states that for a triangle with sides a, b, c and their corresponding opposite angles A, B and C. The following rule holds:

b = length of beginning of submarine to end point. Using sine rule:
