Answer:

The measure of ∠1 is 125° .

Step-by-step explanation:

Definition of vertically opposite angles

As the two lines crosses angle opposite to each other are called vertically opposite angle.

Thus

As the line f and w crosses each other .

∠2 = 55°

∠1 + ∠2 = 180°

(∠1 and ∠2 are supplementary angles there add up sum is 180° .)

∠1 + 55 = 180

∠1 = 180 - 55

∠1 = 125°

Therefore the measure of ∠1 is 125° .

M<1 = 125 degrees. This is because angle 1 next to it say it is angle 3 is 55 degrees. Angle 3 and 1 are supplementary (meaning they add up to 180 degreees). SO you do 180-55 which is equal to 125 degrees.

Answer:

6b^2 +4b

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh

=1/2 (12 b^2 +8b)

= 6b^2 +4b

Greatest common factor of 88 and 48

kupik [55]

GFC is 8. Use a tree of 88 and 48. 88= 2^3 x 11 or 2 x 2 x 2 x 11

48=2^4 x 3 or 2 x 2 x 2 x 2 x 3 see how many groups count as the number once and multiply and bam GFC. Hope I helped! (:

The time that Ellen arrived at the bank was <u>7:02 A.M</u>.

Ordinarily, time is an ongoing and continuous sequence of events that occur in succession, from past through present, and to the future.

For our purpose, we can explain that time is a measure of years, months, weeks, days, hours, minutes, and seconds during which events occur.

Time is also a measure of the distance covered against the speed.

<h3>Data and Calculations:</h3>

The time Ellen left her house was 6:41 A.M.

The time Ellen took to walk to the subway = 10 minutes

Ellen reached the subway station at 6:51 A.M. (41 + 10)

The time that the subway ride took to reach the bank = 11 minutes

Therefore, Ellen arrived at the bank at 7:02 A.M. (51 + 11).

Thus, the time that Ellen arrived at the bank, where she works as a teller, was <u>7:02 A.M</u>.
