This would be easier to explain if I had a paper and a pen, but I will give it a try :=)
Try drawing a picture of the problem and look at it while you read my explanation, it might help :=)
In a cross, the opposite angles will always be the same size, therefore, the opposing angle of the given is 72 degrees. Then we can use the knowledge that one of the unknown and one of the 72 will together be 180 degrees. Therefore, the other angle will be 180-72 = 108 and its opposite will be the same.
So the measures for the other three angles are: 108, 108 and 72.
No.
An integer is a whole number.
In the case of .634 (or 0.634), we see that it is not a whole number, as there is a decimal point, and numbers to the right of the decimal points.
hope this helps
Answer:
The 4 in 153,458 has ten times more the value than the 4 in 192,946.
Step-by-step explanation:
400 and 40
400 ÷ 40 = 10
If a polygon is regular, it has congruent sides and congruent angles. We know that an octagon has 8 sides and a perimeter of 80cm. Because the sides of the octagon are congruent, we can divide 80 by 8 to get <u>10 centimeters for one side. </u> Hope this helps!! :)
Answer:
The numbers are x = 3 and y = 1. Therefore the value of xy is 3.
Step-by-step explanation:
In order to calculate the numbers we will simplify the equation, this is done bellow:
2*x + x(2^2) + (y*2^3) + (y*2^4) = 42
2*x + 4*x + 8*y + 16*y = 42
6*x + 24*y = 42
We can divide the whole equation by 6, so we have:
x + 4*y = 7
The only possible combination of numbers that are positive and integers that will make the equation valid is x = 3 and y = 1. Therefore he value of xy is 3.
