The measure of ∠CBA = 101°.

The sum of the angles is 180°, so to solve, add all of the expressions and equal it to 180°. Then, solve for X by combining like terms, subtractracting 30 from both sides and dividing both sides by 15.

(4x+7) + (11x-9) + 32 = 180

15x + 30 = 180

15x = 150

x = 150/15

x = 10

Then, plug x = 10 into the expression representing anlge CBA.

∠CBA = 11x - 9 = 11(10) - 9 = 101.

Try to prove the hypothesis from part B that the sum of a rational and an irrational number is an irrational number.

Maurinko [17]

The next step of your proof is to subtract (a/b) from both sides.

Then you get, x = (m/n) - (a/b)

Since rationals are closed over addition, (m/n) + (-a/b) is a rational number.

Therefore, x (an irrational number) = a rational number <em>This is a false statement which is a contradiction. So, the assumption was incorrect.</em>

Thus, the sum of a rational and irrational number is an irrational number. QED
