A and B are vertical angles. If m_A = (3x - 30)° and m
Vilka [71]
<h3>Answer:  21</h3>

==================================

Work Shown:

Vertical angles are always congruent.

This means they are equal in measure.

A = B

3x-30 = 2x-9

3x-2x = -9+30

x = 21

--------

Side note:

if x = 21, then,

A = 3*x-30 = 3*21-30 = 33 degrees

B = 2*x-9 = 2*21-9 = 33 degrees

What is the additive inverse of the complex number –8 3i? –8 – 3i –8 3i 8 – 3i 8 3i
Nonamiya [84]

The additive inverse of a number gives zero. The additive inverse of the complex number -8+3i is 8-3i.

<h3>What is additive inverse?</h3>

The additive inverse of a number is the other number which when added to the initial number gives the output as zero.

As we know about the additive inverse, therefore, we need a number that will return zero when added to the complex number.

The additive inverse of the complex number -8+3i will be,

(-8+3i) + (8-3i) = 0

Thus, the additive inverse of the complex number -8+3i is 8-3i.
