Cara multiplied only 4 and 7 together and did not multiply 4 and 13.
Step-by-step explanation:
She didn't distribute the 4 to both numbers inside the parenthesis. If she had done so, she would have gotten 28 - 42, <em>not</em> 28 - 13.
m∠1 = 25° (opposite angles are congruent)
m∠2 = 87° ⇒ 180 - (25 + 68)
m∠3 = 68° ⇒ 180 - (87 + 25)
Hope this helps!
