Answer:
b. -36/77
Step-by-step explanation:
As 0 < x <
/2 => tan x > 0
As 0< y <
/2 => tan y > 0
We have the formula:
As tan x = 1/(cotx) => ![tan^{2}x = \frac{1}{cot^{2}x} =\frac{1}{225/64} = \frac{64}{225}](https://tex.z-dn.net/?f=tan%5E%7B2%7Dx%20%3D%20%5Cfrac%7B1%7D%7Bcot%5E%7B2%7Dx%7D%20%3D%5Cfrac%7B1%7D%7B225%2F64%7D%20%3D%20%5Cfrac%7B64%7D%7B225%7D)
As tan x > 0 => tan x = 8/15
As tan y > 0 => tan y = 4/3
As tan (x-y)=
The answer is -5
Explanation:
-6 + 3 x 4 -11=
-6 + 12 -11=
+ 6 -11 = -5
Answer:
c = -6
d = 2
Step-by-step explanation:
After reflection about the x-axis:
A --> A'
(2,3) --> (2,-3)
(4,3) --> (4,-3)
(2,6) --> (2,-6)
After translation:
(2 + c, -6 + d) --> (-4, -4)
2+c = -4
c = -6
-6+d = -4
d = 2
