What is the measure of A
Rainbow [258]

Given:

A figure of a triangle.

To find:

The measure of angle A.

Solution:

Label the points in the figure as shown below.

In the below figure,

\angle ACB\cong \angle DCE            (Vertically opposite angles)

m\angle ACB=m\angle DCE              (Congregant angles)

m\angle ACB=8x+4

Using exterior angle theorem in triangle ABC, we get

m\angle A+m\angle C=\text{Exterior }m\angle B

m\angle BAC+m\angle ACB=130^\circ

(3x-6)+(8x+4)=130^\circ

11x-2=130^\circ

Isolate the variable term x.

11x=130^\circ+2

11x=132^\circ

x=\dfrac{132^\circ}{11}

x=12^\circ

Now, the measure of angle A is:

m\angle A=3x-6

m\angle A=3(12^\circ)-6

m\angle A=36^\circ-6

m\angle A=30^\circ

Therefore, the correct option is B.

eimsori [14]

Answer:

You never gave the speed of the blue train. The path to collision is equal to 1½ circles. 1.5 x 210 meters = 315 meters I'm going to arbitrarily guess the speed of the blue train is 15 meters per minute. They are therefore approaching each other at a combined rate of 35 meters per minute. 315 / 35 = 9 minutes Answer: 9 minutes

dlinn [17]

Answer: 9,953

Step-by-step explanation:

The first step is to find what the sales tax rate is for the first car because it will be the same for the second.

11,900/767 = .064

Now to find the cost of the second car we divide.

637/.064 = 9,953.125 Round to nearest dollar.
