Answer:
88
Step-by-step explanation:
Sum of angles in a quadrilateral= 360 degrees
<OCA=90degrees [ tangent perpendicular to the circle.
<OBA= 90degrees =tangent perpendicular
to the circle
<OCA + <OBA +92 + <OAB= 360
90 + 90 + 92 + <OAB = 360
272 + < OAB = 360
<0AB= 360- 272 =88 degrees
Y-intercept= (0,2)
x-intercept= (3,0)
Why?
The x-intercept is when y is 0 and y-intercept is when x is 0.
The total distance Tracy traveled was 15,000 feet assuming each unit represents 1,000 feet.
<h3>How to calculate the total distance?</h3>
The total distance is the sum of all the distance between stops.
Partial distances:
- Home to stop 1: 2,000 feet
- Stop 1 to 2: 4,000 feet
- Stop 2 to 3: 5,000 feet
- Stop 3 to 4: 4,000 feet
- Total distance: 15,000 feet
However, the real distance would be 10.63 units based on the locations in the grid.
- d=√(0−8)^2+(7−0)^2
- d=√8^2+7^2
- d=√64+49
- d=√113 =10.63 units
