Answer: A im positive its A
Step-by-step explanation: 3 times 2 equals 6 and add that to 3 times 4 which is 12 and you get 18
Cotangent of angle A=base/height=24/10=12/5
cotangent of B=10/24=5/12
The answer is 3
The question is wrong tho its not the same as the picture
Its not
16x + 181 = 12x
Its
6x +18= 12x
And the solution is
-18 on bothes sides then we have left 6x=12x-18
Then we take -12x on both sides
6x-12x= -18 6x-12x = -6x
-6x=-18
The u divede -18 = -6x
———
-6 -6
Then u get -18/-6= 3 and -6x/-6 = x
x = 3
