What do you need to do to prove a line is an angle bisector of an angle?

1 answer:

3 0

The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides. That is, for any triangle ABC, the bisector of the angle at C divides the opposite side into segments of length x and y such that a/b = x/y.

You travel between these two mile markers and then find your average speed in miles per hour. Which equation does NOT represent

Jet001 [13]

Answer:

The correct option is C.

Step-by-step explanation:

The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.

So total time taken by car is

$4:30-3:00=1:30$

It means total time taken by car is 1.5 hour.

The distance in first figure is 50 miles and the speed in second figure is 155 miles.

So total distance travelled by car is

$155-50=105$

It means total distance travelled by car is 105 miles.

The formula of speed is

$Speed=\frac{Distance}{Time}$

$Speed=\frac{105\text { miles }}{1.5\text{ hours}}$

Therefore option B represents the solution. Option B is incorrect.

Multiply both sides by 1.5 hours.

$1.5\text{ hours}\times Speed=105\text { miles }$

Therefore option D represents the solution. Option D is incorrect.

Divide both sides by speed.

$1.5\text{ hours}=\frac{105\text { miles }}{Speed}$

Therefore option A represents the solution. Option A is incorrect.

Option C can not represent the solution, therefore option C is correct.

How do I graph the line y=2x-3

klemol [59]

Answer:

first, you want to start with the b (-3) graph on the y-axis. after that, since your x is 2 you will start from -3 on the y-axis and go up 2 and to the left once and keep doing that till you run out of space. then go back to the -3 on the y-axis and go down 2 and to the right once

Vol=1348.79cm³. What's X? (Height)

ale4655 [162]

V = PI x r^2 x H

1348.79 = 3.14 x 5.5^2 x H

1348.79 = 94.985 x h
h = 1348.79 / 94.985
h = 14.2 cm ( round answer if needed)
