The shape is a quadrilateral, because it has four sides.
And sum of angles in a quadrilateral = 360 degrees.
The angle with no number but just a symbol = 90 degrees.
From the fourth angle been M:
Therefore: 90 + 62 + 127 + M = 360
279 + M = 360
M = 360 - 279
M = 81
M = 81°

Answer:26 first class stamps and 28 additional.
Step-by-step explanation:
From information given,we can formulate the following equation: 47n +25(54-n ) = 1922
Now we solve for n .
47 + 1350+ 25n =1922
47n -25n =1922- 1350
22n=572
n= 26 .
Therefore 26 first class stamps and 28 additional. 54 total
The equivalent expressions are 6y + 4 and 11y + 16
<h3>How to determine the equivalent expressions?</h3>
<u>Expression (A)</u>
We have:
2y + 4(y + 1)
Open the bracket
2y + 4y + 4
Evaluate the like terms
6y + 4
<u>Expression (B)</u>
We have:
9y + 6 + 2(5 + y)
Open the bracket
9y + 6 + 10 + 2y
Evaluate the like terms
11y + 16
Hence, the equivalent expressions are 6y + 4 and 11y + 16
