We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0
As zero is in the denominator, it can't be defined.
In short, Your Answer would be: "False"
Hope this helps!
It should look like this (x,y). so the x variable goes first and y goes second
3 1/2 miles in 3/4 hour
so to get the average speed per hour = 7/2 * 4/3 = 4 2/3 mph
The answer would be A) The product of a constant factor of four and a factor with the sum of two terms.
The expression 4(y + 6) is the product of two factors: 4 and (y + 6).
4 is a constant factor; the value will remain as 4 regardless of the y value.
The second factor, (y + 6), represents a sum of two terms: y and 6.
Therefore, A is the correct answer.
Observe the given figure.
Here, angle T and R are the inscribed angles.
And sum of inscribed angles is half of measure of intercepted arcs.
Since, the measure of intercepted arcs is 360 degrees.
Therefore, 

Hence, the sum of the two angles is 180 degrees.
Therefore, these are the supplementary angles.
Therefore, angle T and angle R are supplementary angles.
Hence, proved.
