Find the measures of the numbered angle

Angle 5 measures 112.5 degrees

Step-by-step explanation:

Add the three arcs given and subtract from 360 to get the arc intercepted by angle 5.  50+115+85 = 250.  360-250=110.

Take half the sum of that arc and the opposite arc.  110 + 115 = 225.

225÷2= 112.5

i cant see the graph

step-by-step explanation:

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)
