Answer:

The arc measure of BC is 64

Step-by-step explanation:

1. Calculate the full circumference of the circle

C=2pir

=2pi(18)

=36pi

2. Figure out the arc measure

arc length/circumference=arc measure/degrees in a circle

14pi/36pi=arc measure/360 (solve for arc measure)

14pi/36pi *360=140

The measures of BC and CA add up to the measure of BA

mBC +76=140

BC=64

Answer:

x = 11.4 m

y = 21 m

man's shadow =  9.6 m

Step-by-step explanation:

measure of third angle must be 50 degrees (180 - (40 + 90))

you can take tan50° = 15/y and 'y' will equal approx. 21

to find 'x' you can take tan21° = (21-x) /25 and 21 - x = 25 · tan21°

21 - x = 9.6

-x = -11.4

x = 11.4

man's shadow is the difference of 21 and 11.4, which is 9.6

Which graph shows the solution set for Negative 4.4 greater-than-or-equal-to 1.6 x minus 3.6?
____ [38]

Answer:

A number line going from negative 7 to negative 1. A closed circle is at negative 5. Everything to the right of the circle is shaded.

Step-by-step explanation:

-4.4 ≥ 1.6 x - 3.6

Solving for the value of x,

1.6 x ≤ -4.4 + 3.6

 1.6 x ≤ - 0.8

Dividing 1.6 from both sides to know value of x

x ≤ - 0.5
