Answer:
Step-by-step explanation:
Given , start by squaring both sides to work towards isolating :
Recall and :
Isolate the radical:
Square both sides:
Expand using FOIL and :
Move everything to one side to get a quadratic:
Solving using the quadratic formula:
A quadratic in has real solutions . In , assign values:
Solving yields:
Only works when plugged in the original equation. Therefore, is extraneous and the only solution is
Answer: x= 47 (If that says 3x+2)(the picture is a little blurry)
Step-by-step explanation:
Linear pairs of angles sum to 180.
37+(3x+2) =180
Combine like terms
39+ 3x = 180
Subtract 39 from both sides
3x = 141
Divide both sides by 3
x= 47
