BD bisects m m Find m

amm1812

The text of the question is not visible in the answering window. I'll reproduce it here:

BD bisects <ABC.

m <ABD= 2.5x + 8.6

m<CBD = 3.5x - 3.4

Find m<ABC

Answer:

$m\angle ABC = 77.2^\circ$

Step-by-step explanation:

We have an angle ABC and a line BD bisecting it.

If an angle is bisected, then the two formed angles are congruent, that is

$m\angle ABD=m\angle CBD$

Substituting the algebraic expressions for both angles:

$2.5x + 8.6=3.5x - 3.4$

Subtracting 8.6 and 3.5x:

$2.5x - 3.5x = -8.6 - 3.4$

Operating:

$-x = -12$

$x = 12$

The two angles are:

$m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ$

$m\angle CBD=3.5x - 3.4 = 38.6^\circ$

As expected, both angles have the same measure.

The measure of the total angle ABC is twice any of those:

$m\angle ABC = 2*38.6^\circ=77.2^\circ$

$\mathbf{m\angle ABC = 77.2^\circ}$

Jim went by bus to visit his uncle. He left at 10 A.M. and arrived at 4 P.M. The bus traveled 270 mi. What was its average speed

Feliz [49]

Answer:

Average speed, S = 45 mph

Step-by-step explanation:

Given the following data;

Take-off time = 10 AM

Arrival time = 4 PM

Distance = 270 miles

To find the average speed of the bus;

First of all, we would determine the total time.

10 AM to 4 PM = 6 hours

Total time = 6 hours

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting into the formula, we have;

$Speed = \frac{270}{6}$

Average speed, S = 45 mph

Therefore, the average speed of the bus is 45 miles per hour.
