A18 foot wire is tied to the top of a flagpole to a stake in the ground if the stake is 6 feet from the base of the flagpole find the height of the flagpole

I got 12 square root 2 but idk if that's correct so I recommend waiting for another person to answer your question.

Step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
