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.

A puppy and kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 meters per second, while th

Gnom [1K]

It seems it should be the other way... . How soon will the puppy catch up with the kitten.

The way you have it the kitten will never catch the pup. There is already 180m between them so, the distance will only increase because the puppy runs faster than the cat.

If the puppy runs after the cat, will eventually catch up with it and can be calculated. Not the other way around.

If the pup runs after the cat, the distance between them will decrease and the pup will catch the cat.

RT = D kitten

RT = D+180 puppy

20T = D

25T = D + 180

Substitution

25T = 20T +180

5T = 180

T = 36s
