Convert 105 seconds into minutes
60 seconds = 1 minute
105 seconds * 1minute/60 seconds = (105 * 1 minute)/ 60 = 105 min / 60 = 1.75 minutes
The unit that you place in the denominator of your ratio is seconds. This will cancel out the seconds placed in the numerator of 105.
The measures of the angles are given as follows:
<h3>What is the value of x?</h3>
Angle ABD is the sum of angles BCD and ABC, hence:
ABD = BCD + ABC.
We replace the measures to find the value of x, hence:
6x - 9 + 4x - 1 = 82.
10x - 10 = 82.
10x = 92.
x = 9.2.
<h3>What are the measures of the angles?</h3>
With x, we can find the measures of the angles, as follows:
- ABC = 6(9.2) - 9 = 46.2º.
- CBD = 4(9.2) - 1 = 35.8º.

Because: the difference of two squares.
Answer:
![X= 15](https://tex.z-dn.net/?f=X%3D%2015)
Step-by-step explanation:
Since the angles are equal the equation to solve would be:
![3x + 20 = 5x - 50](https://tex.z-dn.net/?f=3x%20%2B%2020%20%3D%205x%20-%2050)
you will subtract 3x from 5x and get 2x
![20 = 2x -50](https://tex.z-dn.net/?f=20%20%3D%202x%20-50)
subtract 20 from 50 to get 30
![2x= 30](https://tex.z-dn.net/?f=2x%3D%2030)
divide each side by 2
![\frac{2x}{2} = \frac{30}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%5Cfrac%7B30%7D%7B2%7D)
![X= 15](https://tex.z-dn.net/?f=X%3D%2015)
