Answer is 98°.
You must add both degrees and then subtract from 180°.


First, we will solve the second equation for
. Subtract
from both sides of the second equation.

Divide both sides of the second equation by
.


Substitute the value of
from the second equation into the first.


We will solve the first equation for
.
Distribute the
to the
.

Combine the like terms.

Add
on both sides.


Divide both sides by
.

Multiply both sides by
.

Substitute the value of
into the second equation.


Multiply.

Add.


<span>So we want to start at 476. Then subtract and add 107 to find the standard deviation increments above and below.
</span><span>476-107=369
</span>369-107=199
199-107=29
