Use a definition, postulate, or theorem to find the value of x in the figure described. ∠abc and ∠cbd are a linear pair. if m∠abc = m∠cbd = (3x − 3)°, find x. select each definition, postulate, or theorem you will use. a linear pair theorem b definition of a linear pair c definition of an angle bisector d angle addition postulate

We know that ∠ABC and ∠CBD are a linear pair. A linear pair includes angles that are formed when two lines intersect.

Linear Pair Theorm states that any 2 angles forming a linear pair are supplementary, i.e. their sum is equal to 180 degree

We also know that m∠ABC = m∠CBD = (3x-3)°

⇒ m∠ABC + m∠CBD = 180°

⇒ (3x-3)° + (3x-3)° = 180°

⇒ (6x-6)° = 180°

⇒ x = 31°

So in the above we have used A and B definition / theorem to determine the answer

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
