Answer:
180=x+139
x=41
90=x+18
x=72
Step-by-step explanation:
the 1st one is a straight line, it is a 180° angle. To find the missing piece, x, you need to do 180-139 and get 41°.
the 2nd one is a right angle (because it has a square at the inner corner), its 90°. To find x, you need to do 90-18 and get 72°
Answer:The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

Answer:
54.5868
Step-by-step explanation:
The multiplicands each have 2 digits to the right of the decimal point, so the product will have 2+2 = 4 digits to the right of the decimal point. The correct placement is ...
54.5868
__
Another way to tell is that the product is in the neighborhood of 3·15 = 45, which is nowhere near 545 or 5458 or any higher value.
Ok all you got to do is divide so that all the numbers will be decimals
hope i helped
