It would take the tortoise 1 minutes and 15 seconds
Answer:
1/8
Step-by-step explanation:
<u>Solving in steps:</u>
- x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
- x/8(x-y) +y/8*(-(x-y))
- x/8(x-y) - y/8(x-y) =
- (x -y)/8(x-y) =
- 1/8
Answer is 1/8
First you need to find the 3rd angle of the triangle
180 - 86 - 46 = 48
and then subtract the answer by 180 (because it’s a straight line)
180 - 48 = 132
so 132
