If mZ DOC = 44º and m2 COB = 80°, find the measure of the indicated arc
in circle 0.
Find DC arc measure.

44°

Step-by-step explanation:

Given:

m<DOC in circle O = 44°

m<COB in circle O = 80°

Required:

Measure of arc DC.

SOLUTION:

<DOC is a central angle that intercepts arc DC. Central angles are said to be congruent to the arc they intercept.

Therefore, m<DOC = measure of arc DC.

Since m<DOC = 44°, the measure of arc DC = 44°.

Arc DC = 44°

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
