2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?

zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

$f(g(x))=f(x+1)=4(x+1)^2$

<u>so C is the correct answer</u>

10$ is spent on 2 big pails and 1 small one. A smail pail cosf half as much as each big one. How much is spent on a big pail? Ho

Mila [183]

Answer:

<u>$4</u> is spent on a big pail and <u>$2</u> is spent on a small pail.

Step-by-step explanation:

Given:

10$ is spent on 2 big pails and 1 small one.

A small pail cost half as much as each big one.

Now, to find the amount spent on a big pail and on a small pail.

Let the cost of a big pail be $x.$

And the cost of small pail be $\frac{x}{2} .$

As given, there are 2 big pails.

And the total money spent = $10.

According to question:

$(x+x)+\frac{x}{2}=10$

$2x +\frac{x}{2}=10$

$\frac{4x+x}{2} =10$

$\frac{5x}{2} =10$

<em>Multiplying both sides by 2 we get:</em>

$5x=20$

<em>Dividing both sides by 5 we get:</em>

$x=4.$

<em>The cost of a big pail</em> = $4.

<em>So, the cost of a small pail</em> = $\frac{x}{2} =\frac{4}{2}=\$2.$

Therefore, $4 is spent on a big pail and $2 is spent on a small pail.
