x=113º

Step-by-step explanation:

67 + x is a linear pair

they would be supplementary if they were next to each other

the 67º represents the acute angle directly next to xº

so

x+67= 180º

subtract 67º from both sides

180-67=113

x=113º

"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
