Since you didn't provide instructions, I am going to assune you are being asked to solve for x. To do this, just distribute and simplify.
2(4x-11)=10
Distribute the 2 to the expression (4x-11)
8x-22=10
Add 22 on both sides
8x=32
Divide by 8 on both sides
x=4
~I hope this helps!~
Step-by-step explanation:
Since ∠E is right angle, its opposite side is DF and the legs are DE and EF.
<u>Pythagorean applied:</u>
D = 5.5p + 25
D: dollars
P: people attending
Tan^-1 (27/48)
x ≈ 29.36°
hope this helps!
