Answer:
D. m =
Step-by-step explanation:
The triangle given is a 30-60-90 triangle. This means that the longer side of the leg is (m), the shorter side of the leg is x (n), and the hypotenuse is 2x.
The hypotenuse is already given as 2, and since the hypotenuse is 2x, to find the shorter side (n), just divide by 2, giving you n = 1.
Now onto the longer side (m); it's represented by , and since x is just 1, all you do is put x in front of .
But in this case, x is just 1, so it's like "imaginary," and doesn't need to be written out.
Answer:
x>2 and x<1
Step-by-step explanation:
first one:
6x+9-9>21-9
6x>12
6x÷6>12÷6
x>2
second one:
9x-5+5<4+5
9x<9
9x÷9<9÷9
x<1
