Answer:
Step-by-step explanation:
<u>Sum of internal angles of a regular polygon is:</u>
<u>We have here 5-sided polygon:</u>
- S = 180*(5 - 2) = 180°*3 = 540°
<u>Now sum the given angles measures and solve for x:</u>
- 3x + 1 + 2x + 15 + 3x - 10 + 3x - 8 + 5x - 2 = 540
- 16x - 4 = 540
- 16x = 544
- x = 544/16
- x = 34°
<u>Find the measure of angle R:</u>
- m∠R = 3x - 10 = 3*34 - 10 = 102 - 10 = 92
- m∠R = 92°

The correct statements about the associative property to create equivalent expressions to a + b + (c + d) are as follows.
The associative property allows us to change the grouping of terms that are added together.
When changing the grouping, the order of the terms stays the same; only the parentheses change position.
The expression a + (b + c) + d is an equivalent expression.
The expression (a+ b) + c + d is an equivalent expression.
Given
Use the associative property to create equivalent expressions to a + b + (c + d).
<h3>Associative property;</h3>
Associative property explains that the addition and multiplication of numbers are possible regardless of how they are grouped.
The correct statements about the associative property to create equivalent expressions to a + b + (c + d) are as follows.

Answer:
Step-by-step explanation: Let w = the width of the given rectangle. Let l = the length of the given rectangle. Since the length l is 3 times the width, then l = 3w. The formula for the area A of a rectangle is: A = lw. It's given that the area A = 60 square inches (in²); t...
