Answer:
d. 15, 30, 135
Step-by-step explanation:
A triangle's interior angles on a flat surface add up to 180 degrees.
a. 90 * 3 = 270 != 180
b.(80 * 2) + 200 = 360 != 180
c.40 + 50 + 60 = 160 != 180
d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
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.
- 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.

Alright, lets get started.
The side of square base is given 0.25 in. (say a)
The height of pyramid is given 1.2 in. (say h)
The formula for surface area A is given below:
A=a^2+2a √(a^2/4+ h^2 )
Putting the value of a and h .
Putting the value of a and h
Hence the area of pyramid is 0.6625 square inches. : Hope it will help :)
