In triangle xyz, what angle is included between segment xy and segment xz?

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

their is no graph showing

step-by-step explanation:

it would open into a square depending on the type of envelope i’m not sure about the second part

"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
