If tan fº = 2/1 and the measure of yw is 8 units, what is the measure of xw?

erma4kov [3.2K]

*see attachment for the figure referred to

Answer:

4 units

Step-by-step explanation:

Given that $tan(f) = \frac{2}{1}$ , therefore, it follows that:

$tan(f) = \frac{opp}{adjacent} = \frac{YW}{XW} = \frac{8}{XW}$ ,

If the ratio of YW to XW = 2:1, therefore, $\frac{2}{1} = \frac{8}{XW}$

Cross multiply to find XW

$XW*2 = 8*1$

$XW = \frac{8}{2} = 4 units$

y = –6x 2 –12x – 2y = –4 how many solutions does this linear system have? one solution: (0, 0) one solution: (1, –4) no solution

lara [203]

Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4

Therefore, the system has infinite number of solutions.
