Quick answer, please. This would really help me out.

Given:

Circle with chord and tangent.

To find:

The measure of angle 1.

Solution:

Let 2 be the adjacent angle of angle 1.

If a tangent and a chord intersect at a point, then the angle formed is half of the measure of the intercepted arc.

Sum of the adjacent angles in a straight line is 180°.

⇒ m∠1 + m∠2 = 180°

⇒ m∠1 + 124° = 180°

Subtract 124° from both sides.

⇒ m∠1 = 56°

The measure of angle 1 is 56°.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
