The table gives the velocity readings for a car moving in a straight line. Estimate the total distance covered, using left endpoints. Time (s) `"Velocity" ((ft)/s)`
1 20
3 35
5 52
7 78
9 120

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

answer: entity is prob the answer

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
