Answer:

∠B = 41°

Step-by-step explanation:

<u>Step 1</u>: Recognize that ∠B and ∠A are "remote interior angles" with respect to the exterior angle at C. Hence their sum will be equal to the measure of the exterior angle.

<u>Step 2</u>. Compute angle B as the difference between the exterior angle at C and the interior angle at A:

113° - 72° = ∠B = 41°

6x2 +10x−1 discriminant

eimsori [14]

Answer:

$124$

Step-by-step explanation:

$6 {x}^{2} +10x−1$

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

${b}^{2} −4(ac)$

Substitute in the values of a, b, and c.

${10}^{2} −4(6 \times (−1))$

$100−4(6(−1)$

$100−4(−6)$

$100 + 24$

$124$
