Answer:
5y-x-10 = 0
Step-by-step explanation:
The measurement of angles are: 20°, 60° and 100°
Step-by-step explanation:
Let x be the first angle
Then according to the ratio
1:3:5
The angles will be x,3x,5x
We know that the sum of interior angles of a triangle is 180 degrees
So,

Dividing both sides by 9

The angles are:
First angle = x = 20°
Second angle = 3x = 3*20 = 60°
Third angle = 5x = 5*20 = 100°
Hence,
The measurement of angles are: 20°, 60° and 100°

Answer:
A
Step-by-step explanation:
Mode is the one that appears the most. The number that is there the most is 20 that makes it the mode.
Hi!
Let's just take this part by part.
The sum of seven is the first part written. You can deduce from that, that it's 7 + something.
The next part is the quotient of a number x and 8. A quotient is the result of something being divided, so we can figure out that it's x / 8.
Putting it all together, you get the expression as 7 + x / 8.
Hope this helped!
The square root of 120.6 would be 10.98 but we rounded to 11, hope this helps
