Answer:

The measure of ∠A is 66°.

Step-by-step explanation:

We know that:

∠A = 3x + 18
∠D = 4x + 2
∠D = ∠A

Now, let's solve the equation. ∠D = ∠A.

=> 3x + 18 = 4x + 2
=> -2 + 18 = x
=> 16 = x

Now, let's substitute the value of x into any equation.

=> 4x + 2
=> 4(16) + 2
=> 66°

Hence, the measure of ∠A is 66°.

The square root of 12 is irrational. True False

dalvyx [7]

True.

The square root of 12: √12 = 3.464101......

This continues indefinitely and can not be represented as a ratio of two integers.

So it is not rational, that is irrational.
