Answer:
Which of the following sets of possible side lengths forms a right triangle?
<h3><em><u>11, 60, and 61</u></em><em><u>✓</u></em></h3>
6, 12, and 13
9, 40, and 45
12, 35, and 38
Step-by-step explanation:

<h3>11, 60 and 61 is the right answer.</h3>
Answer:
-2
Explanation:
f = -19.8
17.8 + -19.8 (f) = -2
X/ 6.9 = 5/6
x = 6.9(5) / 6
x = 5.75
x = 5.8
or
x/ 6.9 =6/5
x = 6.9(6) / 5
x = 8.28
x = 8.3
answer is D.
8.3 cm , 5.8 cm
<h3>It'd be C. To find mean, you first add all the terms, than divide by how many terms there were. 12+8+7+10+8+8+10=63, and there are 7 terms, so 63÷7=9.</h3>
