Answer:
Q1. Regular (A)
Q2. 105° (C)
Q3. x=45°
Step-by-step explanation:
Q1. A regular polygon is a polygon with all sides and angles equal.
Q2. The sum of the measure of exterior angles of a polygon is always 360°. Therefore, 360°-255°=105°
Q3. 148°+112°+(2x+10)°+(2x)°+90°= Sum of angles in a pentagon.
<u><em>Note</em></u>: The square at the fifth angle shows that its a right angle which is 90°. Also all the angles are equal to the sum of angles in a pentagon 'cause the polygon has 5 sides ( a pentagon).
Sum of interior angles of a polygon is: (n-2)180°. Where "n" is the number of sides of the polygon.
Therefore the sum of interior angles is (5-2)180°=540°
solving the equation you have;
360°+4x=540°
4x=540°-360°
4x=180°
x=180°/4
x=45°
therefore x=45°
Answer:

Draw a line on the hole which forms a square. The square lengths are 3 inches because 12-9 equals 3. 3^2= 9 which is the area of that square below the rectangle. Draw another line to separate the big rectangle into two rectangles. The smaller of these two new rectangles dimensions are 4 by 7 in. 7x4= 28 ft as the area of the smaller rectangle. The dimensions are the larger rectangle are 4 by 9 inch. The area of the larger rectangle is 36 inches.
36+28+9=73 in^2 as the total area.
