Step-by-step explanation:
Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode

What you have to do is rearrange the equation by subtracting what is on the right of the equal sign from both sides of the equation
so it would be 4*x-13*x-(27)=0
