Answer:
(A) 70°
(B) 67°, because they are alternate interior angles
Step-by-step explanation:
<em>For a:</em>
The angles of a triangle will all add up to 180°. Using the "feathers" (lines that signify congruence), we can tell that the angle connecting the two congruent lines will be different than the other two, which will be equivalent to each other.
This means that the angle measure of x will be , or just .
This is equal to 70°.
<em>For b:</em>
We know that the 67° angle and y are formed by the same line intersecting two parallel lines. This means that the angle measures of each intersection point will be the same as the other intersection point, however they will be flipped. This makes the concept of alternate interior angles. We know that the 67° angle and y are formed by the same line, this means that their angle lengths are the same - therefore y is 67°.

Answer:
18.75%
Step-by-step explanation:
(round answer if needed)
The number in the front always goes up by one/1,2,3,4
Kim ran total 7.1 miles.
Further explanation:
Front end estimation is the specific technique for rounding off numbers to estimates sums and differences. The numbers to be added or subtracted are rounded off to nearest one, tenth and hundredth.
So in the given scenario, we will round off to the nearest tenth.
So,
2.76 miles will be rounded off to 2.8 as the number right to the digit 7 is greater than 5, 7 will be rounded off to the next digit.
2.34 miles will be rounded off to 2.3 as the number right to 5 is less than 5, so 3 will be as it is.
1.97 miles will be rounded off to 2.0 as the number right to 9 is greater than 5 so it will be rounded off to the next number.
So, after estimation

Answer:
the number of days when instructor do the work alone is 8 days
Step-by-step explanation:
Given that
The apprentice can do the work in 24 days
And, the apprentice and instructor together can do it in 6 days
We need to find out the number of days when instructor do the work alone
So,
hence, the number of days when instructor do the work alone is 8 days
