The answer is 122 for the final angle
Just did one just like it
688.32 = x + .043 x + .0325 x = 1.0755 x
x = 688.32/1.0755 = $640.00
Answer: $640.00
Check: 640(1+.043+.0325)= 688.32 good
Questions are USUALLY answered within 10 minutes.
Therefore, you're questions might be complicated, hard, or incomplete.
Actual people are answering these questions, so obviously the easier questions get answered first.
<u>Let's take this problem step-by-step</u>:
<u>The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'</u>
⇒ is on a straight line
⇒ sum of angle measure = 180 degrees

<u>Now we know:</u>
⇒ sum of all angles in a triangle ⇒ 180°
<u>Let's put that in equation form and solve:</u>

<u>Answer: 21°</u>
<u></u>
Hope that helps!
