Answer:
X=15
Step-by-step explanation:
Subtract
3x-3 18-3
x=15
Short leg = x-6m
Longer leg =x
Hypotenuse = x+6m
x² + (x-6)² =(x+6)²
x² + x²-12x+36 = x²+12x+36
2x²-12x+36= x² +12x+36
2x²-12x+36-36= x² +12x+36-36
2x² - 12x-12x = x²+12x-12x
2x² -24x-x² = x²-x²
x² -24x = 0
x(x-24)=0
x = 24
Short leg = 24-6m = 18
Longer leg =24
Hypotenuse = 24+6m=30
Check
a² + b² = c²
18² +24² =30²
324 +576 = 900
900=900
No, I simply apply t=2 to the equation 16t2, and get 64 which is less than 75ft, so it would take longer time to hit the ground. So the answer is no I think.
Answer:
x=6
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2
(9+3) * 3 = x^2
12*3 = x^2
36 = x^2
6 = x
