Yeah the first one (A) seems like the best to me :)
Answer:
11 is correct
12 should be 51°
Step-by-step explanation:
15/sin(104) = 12/sin(J)
J = 50.917°
You can use keep it change it flip it and do:
7/10•9/5=63/50= 1 3/50
7•9=63
10•5=50
Hope this helped
A
4+8=12 wrong
4.5+8=12.5 wrong
5+8=13 wrong
5.5+8=13.5 right
the rest of the numbers are above 5.5 so they aren't wrong
<u>5.5, 6 and 6.5 makes the inequality true
</u>
B
x+8>13
x>13-8
<u>x>5
</u>
C
<u>x=5 is not a solution to the inequality because 5+8 is not more than 13.</u>
