The ladder forms the hypotenuse of a right triangle. Solve for a
<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 9^2 = 18^2 </span>
<span>a^2 + 81 = 324 </span>
<span>a^2 = 243 </span>
<span>a = 15.589 = 15.6 feet</span>
Answer:
1:3 or 1/3
Step-by-step explanation:
Because 3/9=1/3.
27. Do 36/2 which equals 18 and multiply that by 3. Then divide that number by 2.
3x - 1 = 5x - 11
Add 1 to both sides.
3x = 5x - 10
Subtract 5x from both sides.
-2x = -10
Divide by -2.
x = 5
