A soccer ball is placed 15 feet away from a goal post that measures 8ft high. You kick the ball and it hits the crossbar at the top the goal. What was the angle of elevation of you kick?

what

answer: what are the following choices

"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

your answer would be b
