If sin of theta equals 0.1 and theta is in the second quadrant . what are cos and tan of theta?

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

"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

its kinda hard to answer this when we dont have all the information that we need.
