<em>Complementary= 90 Degrees </em>
<em>Equation: x + x = 90 </em>
A = x
B = x + 32
<em>2x = 90 - 32 </em>
<em>2x = 58
</em>
<em>x = 29
</em>
<em>Angle A = 29 degrees
</em>
<em>Angle B = 61 degrees.</em>
A because it has to be less than or equal to 143.15 so it can not be C or D. And you dont need the extra x so it is choice A
The additive inverse of a number is that number with its sign changed.
The additive inverse of 5/8 is -5/8, so that is the value of <em>m</em>.
The sum of a number and its additive inverse is <em>zero</em>. (This is actually the definition of <em>additive inverse</em>.)
5/8 is found at 5/8 on the number line.
m is found at -5/8 on the number line.
"sum" is found at 0 on the number line.
