Answer:
23 should have been subtracted from, not added to, both sides of the equation.
3/4(1/2x + 4) + 1/2(x − 1)
First use distributive property to remove the parentheses:
3/8x + 3 + 1/2x -1/2
Now combine like terms:
7/8x + 2 1/2
1 - √3 cot (x + 15) = 0
√3 cot(x + 15) = 1
tan (x + 15) = √3
x + 15 = 60
x = 45 degrees answer
