Answer:
Step-by-step explanation:
The angles of a triangle add to 180°, so the acute angles of a right triangle add to 90°. This is one relation between the angles that can be made in to an equation.
Another relation that can be used to make an equation is the given fact that one angle is 4 times the size of the other.
The equations above express these relationships.
(4x - y)/(2y + x) when x = 3 and y = 3 is
(4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
Answer:
What are the numbers?
Step-by-step explanation:
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.
