Answer: Y=8
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, find the slope, m, and y-intercept, b, of line t.
Slope (m) = CD/BD
Slope (m) = 4/6 = ⅔
y-intercept is y = 1. This is where the line intercepts the y-axis. So, b = 1.
Substitute m = ⅔, and b = 1, in .
Thus, the equation for line t would be:
Find cos using trig identities:
Therefore
Sub in tan x = 3, (Note that x is in 3rd quadrant, cos x < 0)
Finally, sub into Half-angle formula:(Note x/2 is in 2nd quadrant, tan x<0)
Answer:
5 hours
Step-by-step explanation:
39 - 14 = 25
5 x 5 = 25
14 + 25 = 39
