What is the measure of angle x, in degrees, in the figure shown? a triangle with angle measure 60 degrees and 53 degrees. the third angle has an unknown measure, x degrees.

x = 67

Step-by-step explanation:

60+53+x = 180

The degrees of a triangle always equal 180

113+x = 180

Subtract the 113 from the 180

x= 67

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)
