A park in the shape of a right triangle, one leg of the triangle is 2 kilometers long, the hypotenuse measures 2.9 kilometers ho
w long in kilometers is the other leg?
1 answer:
Answer:
2.1 kilometers
Step-by-step explanation:
Pythagoras' Theorem
a^2 + b^2 = c^2
2^2 + b^2 = 2.9^2
2.9^2 - 2^2 = b^2
8.41 - 4 = 4.41
b = √4.41
b= 2.1

50+ 7.99 x =y
50+ 7.99 (40)= y
50+319.60= y
369.60=y
50+ 7.99 x =y
50 + 7.99 (50)
50+ 399.50=449.50
6.99(30)=209.70
449.50 + 209.70 =659.2
2x + y = 0
2x + 3 = 0
- 3 - 3
2x = -3
2 2
x = -1¹/₂
(x, y) = (-1¹/₂, 3)
