All positive numbers have a square root, and a square root is defined as the number you can multiply by itself to get the original number.

In this case 9 x 9 = 81, which means that 9 is a square root of 81. However, if you multiply two negative numbers, you get a positive number. This means that every positive number has a square root that is positive and negative.

-9 x -9 = 81

The answer is -9 and 9

What is the measure of angle B in the triangle?<br>will give brainliest
spayn [35]
The angles of a triangle always add up to 180°.

120 + x + 16 + x = 180

Add up the values.

136 + 2x = 180

Subtract 136 from both sides.

2x = 44

Divide both sides by 2.

x = 22

Answer:

2.5

Step-by-step explanation:

The minimum value is the minimum y-value a function includes. In this case, since you can see the function is periodic (it repeats itself <em>periodically</em>, hence periodic) and the smallest y-value the function encounters is 2.5 (doesn't go below this value), the minimum y-value is 2.5. I hope this made sense. If not, feel free to let me know.
