Answer:
3√7
Step-by-step explanation:
9²+B²=12²
simplify
81+B²=144
minus the 81
B²= 63
90/2 = 45
45/1700 = 0.02647
0.02647 x 100 = 2.64
2.46%
Answer:
Step-by-step explanation:
If by opposite you mean...
1 opposite is -1

"one" will fill both blanks.
Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.
