How do you this??<br><br> Scientific notation
Airida [17]
So Scientific Notation is a "simplified version" of a number. For example, is your number is 2,345, the scientific notation would be 2.345 * 10³. 

If it was 0.023, then the scientific notation would be 2.3 * 10^-2. 

Scientific notation is found by moving the decimal place to the left or right, until only one digit is left to the left of the decimal; it has to be greater than 1, but less than ten. If you move the decimal place to the right, it's a negative power of 10. If you move it to the left, it is a positive power of 10.


Hope this helps!

Answer:

36.2

Step-by-step explanation:

Assuming that the dotted line is a perpendicular bisector, we can say that it splits the side that is 30 units long into 2 sets of 15 units. Then, we can use the pythaogrean theorem to solve (Leg A is 33 and Leg B: 15). a^2+b^2=c^2

33^2+15^2=c^2

1089+225=c^2

1314=c^2

Square root of 1314 = square root of c^2

36.2 aapproximately c
