Answer:
Step-by-step explanation:
The identical arc symbols on the two angles indicates the angles are congruent. Also, these are alternate interior angles where a transversal crosses lines marked as parallel, so they are congruent:
∠A = ∠B
8x +78° = 2x +114° . . . . . substitute the given expressions
6x = 36° . . . . . . . . . . . . . subtract 2x+78° from both sides
x = 6° . . . . . . divide by 6
∠B = 2x +114° = 2·6° +114° . . . . . put the value of x into the expression
∠B = 126°

Answer: 939,520
Step-by-step explanation: To round 939,515 to the nearest ten, we first find the digit in the rounding place which in this case is the 1 in tens place.
Next, we look at the digit to the right of of the 1 which in this case is 5.
According to the rules of rounding, since the digit to the right of the rounding place is greater than or equal to 5, we round up.
This means that we add 1 to the digit that's in the rounding place so 1 will become 2 and we change all the digits that appear to the right of the rounding place to 0.
So 939,515 rounded to the nearest 10 is 939,520.

Answer: Hi!
To find the volume of a box (or cube), you multiply length times width times height.
In this case, you have all of the measurements, so all we have to do is multiply them together!
5cm * 8cm * 10cm = 400
So, the volume of this box is 400cm^3!
Hope this helps!
