<u>Answer</u>

x = 12


<u>Explanation</u>

The two given angles are supplementary angles. That means that the add up to 180 degrees.

(5x + 5) + 115 = 180

5x +5 + 115 = 180

5x + 120 = 180

5x= 180 - 120

5x = 60

x = 12

What's the simplest form of 10/1​
kupik [55]

Answer:

1 s / 6 s

Step-by-step explanation:

Since you have different units of measurement (seconds and minutes) you have to get them to be the same unit.

Change the 1 minute into seconds.

1 min = 60 sec

Now simplify the new fraction.

10 s / 60 s

10 can go into both the numerator and the denominator.

1 s / 6 s
