Answer:

48 degrees

Step-by-step explanation:

The sum of 42 and x should get 90 degrees, so if you subtract 42 from 90 you get 48.

Hope this helped :)

Answer:

Step-by-step explanation:

Just like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. Sometimes we can determine a missing angle because we know that the sum must be a certain value. Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees.

The angles of this triangle are 50, 60, and 70 degrees.

If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.

450

If he used 1/3 of the stock bottle, then you have
150=1/3x

Now, you multiply both sides by 3, which gives you

450=x

So, originally there were 450 bottles in the stock bottle

Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus
natka813 [3]

Answer:

Identity property of multiplication

Step-by-step explanation:

From step 5:

1x = 20

Here, to solve for x so that the variable x stands alone, Alberto uses the identity property of multiplication, which justifies what he has in step 6.

Step 6:

x = 20

According to the identity property of multiplication, any value you multiply by 1 gives you that same value.

Therefore, 1x = 1 × x = x.

The variable x multiplied by 1 will give you x.

Jaime drew the number line below to show 2/3 4/5. Explain how the number line shows 2/3 times 4/5. What is the product?
bearhunter [10]

Answer:

\frac{2}{3} * \frac{4}{5} = \frac{6}{15}

Step-by-step explanation:

Given

\frac{2}{3} * \frac{4}{5} =

The number line is missing from the question.

So, I will answer the question and also draw the number line to show the product.

\frac{2}{3} * \frac{4}{5} =

\frac{2}{3} * \frac{4}{5} = \frac{6}{15}

To represent this on a number line;

We draw a number line of 15 points, and place a dot on the 6th point.

This represents 6/15
