Answer:
x ≈ 17.14
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan35° = = ( multiply both sides by x )
x × tan35° = 12 ( divide both sides by tan35° )
x = ≈ 17.14 ( to the nearest tenth )
Answer:10
-3x² +6x -1 = 0
x2 - 2x + = 4(x2-2x +1)-3
x² - 2x = 4x²-8x +4 - 3
x²-4x²-2x+8x = 4-3
-3x² +6x = 1
