<h2>(3x+4)+2(3x+4)=117</h2>
<h2>= (3x+4)+(6x+8)=117</h2><h2>= 3x+4+6x+8=117</h2><h2>= 9x+12=117</h2><h2>= 9x = 117-12 </h2><h2>= 9x = 105</h2><h2>= x =105 ÷ 9</h2><h2>= x = 11.6666666667</h2>
<h2>Hence,x = 11.6666666667</h2>
Answer:
Step-by-step explanation:
y = arctan(x+pi/2) use that tan y = x is y= arctan x
tan y = x+pi/2; change x with y and find y
tan x= y +pi/2; subtract pi/2 from both sides
-pi/2 + tan x = y
y= tan x -(pi/2) is the inverse function
you can also write it as
y = 1/2(2 tan x -pi)
