Consider the given statement:
8+3.4=3.4+8
We have to identify the property used in this statement.
1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that 
. This property is not used in the given statement.
2. Inverse property of addition: A number 'a' is said to have an inverse '-a' if 
. This property is not used in the given statement.
3. Inverse property of multiplication: A number 'a' is said to have an inverse '
' if 
. This property is not used in the given statement.
4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that 
.
In the given statement, 8+3.4=3.4+8
which is expressed as 8+12 = 12+8, this statement holds commutative property of addition as whether 8 is added to 12 or 12 is added to 8, the result is same.
So, Commutative property of addition is illustrated in this statement.
I think the answer is B. because the sum of the 2 smaller numbers is greater than the 3rd number.
a. 8+6 = 14 ; 14 is less than 16 ; wrong
b. 8+6 = 14 ; 14 is greater than 10 ; correct
c. 7+6 = 13 ; 13 is less than 14 ; wrong
d. 6+7 = 13 ; 13 is less than 20 ; correct
Hope this helped☺☺
<span>Suppose a triangle had two right angles.
The sum of all angles of any triangle is 180</span>°.
The measure of a right angle is 90°.
By difference, the measure of the other angle can be determined.
Since the two angles have a measure of 90° each, then by difference, the measure of the third angle is 180° - (90° + 90°) = 0°.
If the angle is 0°, there would only be two sides.
A triangle has three sides.
Therefore, a triangle can't have two right angles.
