Answer:
The cost of a pair of trousers and a shirt is $46 and $3 respectively.
Step-by-step explanation:
Let us assume the pairs of trousers be X
And, the pairs of trousers be Y
So, the first equation is
2X + 3Y = $101
And, the second equation is
7X + 3Y = $331
Now substituting this two equations
2X + 3Y = $101
7X + 3Y = $331
-5X = -$230
X = $46
Now put the X values in one of the equation to find out the Y value
So,
2 × $46 + 3Y = $101
$92 + 3Y = $101
Y = $3
It can be true when we have a regular polygon whose all sides are equal that results in making equal angles inside it. Each of the interior angles in a polygon are equal in measure is true sometimes. But for other polygons, this is not true. So the correct answer is "sometimes"
Sometimes- Each of the interior angles in a polygon are equal in measure.

Step-by-step explanation:
i think the answer is 112°.......
1/2 b-39=101
+39 +39
1/2 b= 140
2(1/2) b= 140(2)
b=280
