500 / 2 = 250 miles per hour ( rate of speed)
250 * 8 = 2,000 miles in 8 hours
Answer:
angle a = angle bac = 90 degrees
angle b = angle abc
angle c = angle acb
Answer: the answer to your question is
Recall that when you multiply a decimal by a power of ten (10, 100, 1,000, etc), the placement of the decimal point in the product will move to the right according to the number of zeros in the power of ten. For instance, 4.12 · 10 = 41.2.

The correct option is: 20
<u><em>Explanation</em></u>
The expression
can be rewritten as
That means: 
Now simplifying the left side, we will get....

Now <u>comparing the co-effcients of like terms in left and right side</u>, we will get.....

Thus, the value of 't' will be 20.
The answer would be 29* because the two measurements should be equal to 180*. So the value of one angle plus the value of the other angle equal 180. You gather all like values in the equation, then leave the x by it self by dividing. After you have the final x value, you substitute x to the initial values to give the final angle results.
