Top triangle: if the know angle measures are 90 and 55 and there are a total of 180, 90 + 55 + a = 180. This means that angle a = 35°
Bottom triangle: if a is 35, the angle connected to it is 35 because they are vertical angles. The angles of this triangle are 35 + 120 + b = 180. Angle b = 25°
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:
Where, 
are parallel sides and 
is the vertical distance between the parallel sides.
Putting 
in the above formula, we get
Therefore, the area of the trapezium is 408 square cm.
Step-by-step explanation:
The digital root of a number is the single digit that you get by adding all of the digits of the original number together. If the result of that is multiple digits, you add those digits together, repeating the process until you get a single digit. That digit is the digital root of the original number.

Answer:
50,000 ≤ 23,210 + 5x
x = Average number of words per week
Step-by-step explanation:
Start off with 50,000 because that's how many words the paper needs to have.
Use "≤" because Trevor needs to write at least 50,000 words. (He can write more).
Trevor already wrote 23,210 words plus x words per week for 5 weeks.
(Solving for x will help you find the average number of words Trevor must write per week for 5 weeks).
