Answer:
a= 37
Step-by-step explanation:
All the angles of a triangle add up to 180° so if you add 110 with 35 it equals 145, then subtract 145 by 180 and you get 37
You can multiply 8 times 9 to get 72 and then move the decimal over to the right to get the answer of 7.2

Answer:
$49
Step-by-step explanation:
<u><em>Method 1</em></u><u><em>:</em></u>
100% - 65% = 35%

y · 100 = 35 · 140
100y = 4900
100y ÷ 100 = 4900 ÷ 100
y = 49
<u><em>Method 2</em></u><u><em>:</em></u>

y · 100 = 65 · 140
100y = 9100
100y ÷ 100 = 9100 ÷ 100
y = 91
$140 - $91 = $49
