Answer:
y = 38°
Step-by-step explanation:
If Angle x and angle y are complementary, then x + y = 90°
Also, if angle x is supplementary to a 128 angle, then x + 128° = 180°.
Solving the latter equation for x, we get x = 52°.
Therefore, by the first equation, x + y = 90° becomes 52° + y = 90°, yielding
y = 38°
Answer:
497/1000
Step-by-step explanation:
sorry but that's as simplified as it gets
Rate x time = distance
b = rate boat travels in still water
c = rate of the current
(b-c)4 = 216
(b+c)4 = 304
4b - 4c = 216
4b + 4c = 304
___________
8b = 520
b = 65 Km/hr
4c = 304 - 4b = 304 - 260 = 44
c = 11 Km/hr

<h2>
Equation of line with slope m is</h2><h3>
y-y1= m(x-x1)</h3>
here (x1,y1) are the points given to you
m is the slope
i will solve 1st one for you
y-(-7)=(-3)(x-2)
y+7=-3x+6
3x+y+1=0
