7. TOWERS A lookout tower sits on a network of struts and posts. Leslie measured two angles on the tower. If m∠1=7x-7°, m∠2=4x+2

yaroslaw [1]

The angles in a triangle add up to 180 degrees

The measure of $\mathbf{\angle 1 }$ is $\frac{1162}{13}$

The given parameters are:

$\mathbf{\angle 1 = 7x - 7}$

$\mathbf{\angle 2 = 4x + 2}$

$\mathbf{\angle 3 = 2x + 6}$

The angles form a triangle.

So, we have:

$\mathbf{\angle 1 + \angle 2 + \angle 3 = 180}$

This gives

$\mathbf{7x - 7 + 4x + 2 + 2x + 6 = 180}$

Collect like terms

$\mathbf{7x + 4x + 2x = 180 + 7 - 2 - 6}$

$\mathbf{13x = 179}$

Divide by 13

$\mathbf{x = \frac{179}{13}}$

Substitute $\mathbf{x = \frac{179}{13}}$ in $\mathbf{\angle 1 = 7x - 7}$

So, we have:

$\mathbf{\angle 1 = 7 \times \frac{179}{13} - 7}$

$\mathbf{\angle 1 = \frac{1253}{13} - 7}$

So, we have:

$\mathbf{\angle 1 = \frac{1253 - 13 \times 7}{13}}$

$\mathbf{\angle 1 = \frac{1162}{13}}$

Hence, the measure of $\mathbf{\angle 1 }$ is $\frac{1162}{13}$

How would you find the volume of a tower created from 1,000 cans that were each 12oz in volume?

vlabodo [156]

Answer:

Multiply the number of cans by the volume of each: 12,000 oz.

Step-by-step explanation:

You find the total volume of more than one can by adding the volumes of the cans involved.

For 2 cans, the volume would be ...

12 oz + 12 oz = 24 oz

__

When you consider adding numbers more than a couple of times, you start looking for ways to simplify the effort. Multiplication was invented for that purpose. Here, multiplying the volume of 1 can by 1000 is the same as adding the volumes of 1000 cans.

For 1000 cans with volume of 12 oz each, the volume of the total is ...

1000 × 12 oz = 12,000 oz.
