Answer:
The answer is option A.
<h2>50 degrees</h2>
Step-by-step explanation:
To find angle C we use the cosine rule
That's
AB² = AC ² + CB ² - 2(AC)(CB)cos C
AC = 7.5
AB = 6
CB = 6.5
6² = 7.5² + 6.5² - 2(7.5)(6.5)cosC
36 = 56.25 + 42.25 - 97.5cos C
36 - 98.5 = - 97.5 cos C
-62.5 = - 97.5 cos C
cos C = -62.5 / - 97.5
C = cos ^-1 25/39
C = 50.1
The final answer is
<h3>C = 50°</h3>

8 x 5 x 4= 160
1890/160= 11.8195
Rounded: 11.82
The answer would be equal. If you add 10% to 100 and subtract 10% from your total answer you'll get 100 again.

The correct question is
<span>What is the approximate circumference of the largest circle that could be cut out of an 8 1/2-inch by 11-inch piece of paper? use 3.14 for p and round to the nearest inch?
we know that
the circumference=pi*D
where D is the diameter
dimensions piece of paper
8 1/2 in x 11 in----> 8.5 in x 11 in
so
</span><span>The longest diameter (that remains on the paper) would be 8.5 inches
circumference=3.14*8.5-----> 26.69 in------> nearest inch----> 27 in
the answer is
27 in</span>
