What is the value of x

HELP

7

Step-by-step explanation: This is an equalateral triangle. You can tell by the marks on each angle, marking that they are equal.

This means that the two sides that aren't the hypotenuse are the same.

Therefore,

Multiply out the 4

Subtract 8

Divide by 4

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

the answer is 96 degrees
