Step-by-step explanation:
You should study the exponential laws. Remember that (a/b) to the exponent of m is the same as a to the exponent of m over b to the exponent of m.
Therefore, 2 to the exponent of 5×4 over 3 to the exponent of 2×4 equals to 1048576/6561.
The measure of the angle ∠ABC will be 40 degrees. Then the correct option is B.
<h3>What is a circle?</h3>
It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
In the diagram, the measure of the arc from A to B not passing through C is 80 degrees.
Then the measure of angle ACB will be
We know that Angles subtended by the very same arc at any position on the circular path are half of the angles subtended by the very same arc at the centre.
Then we have
2∠ABC = ∠AOB
2∠ABC = 80°
∠ABC = 40°

Answer:
Step-by-step explanation:
The angle of a line is 180 degrees. A right angle is 90 degrees, and the given angle is 55 degrees. All you have to do is add 90 and 55, and subtract that sum from 180.
You can get the answer by subtracting the time it took Mark to cut the grass from the total amount of time it took him to do the chores. So 4 hours and 40 minutes minus 1 hour and 45 minutes is 2 hours and 55 minutes
