The degree measure of the diameter and the degree measure of the semicircle are the same.
Step-by-step explanation:
Diameter is the chord passing through the centre of the circle. It is the longest of all the chords of a circle. Semicircle refers to half circle. It is to be noted that semicircle has its base on the circle's diameter.
As we know that the angle measure of the diameter is 180 degrees (since diameter is also a straight line whose angle equals 180 degrees )
Similarly, the degree measure of the semicircle is half of the complete circle i.e. 360/2= 180 degrees.
Thus, angle subtended by the diameter is same as that of the angle made by the semicircle.
Answer: 30 minutes
Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.
Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.
Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>
We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.
Therefore, 2/4 of an hour is 30 minutes.
The answer is 7.68.
Hope this helps.

Answer:
Step-by-step explanation:
Remember that three points are collinears if they stay in the same line.
To find the line that pass through A(-2,3) and A''(3,7), we find first the slope of the line and then the y-intercept.
The slope of the line is
The y-intercept of the line is
Then the equation of the line is
Since we want that the point A'(x,y) stay in the line, then we need to choose a value for x and replace in the equation found.
If we take x=2
Then the points are collinear.
