Answer:

x = 117°, 297°

Step-by-step explanation:

Subtract 1 from both sides of the equation and you have ...

tan(x) = -2

Then the arctangent function tells you ...

x = arctan(-2) ≈ 116.5651°, 296.5651°

x ≈ 117° or 297°

For all values of x, f(x)=2x^2 and g(x)= x+1<br> Solve fg(x) = gf(x)

Andrej [43]

Answer:

-0.25

Step-by-step explanation:

→ Find fg(x)

2 ( x + 1 )² = 2x² + 4x + 2

→ Find gf(x)

2x² + 1

→ Equate them

2x² + 1 = 2x² + 4x+ 2

→ Move everything to the right hand side

0 = 4x + 1

→ Solve

x = -0.25

Answer:

∠K = ∠M = 55°

Step-by-step explanation:

The two marked angles are opposite the sides marked as congruent. That means the angles are congruent, so we have ...

4x -1 = 2x +27

2x = 28 . . . . . . . . add 1-2x to both sides

x = 14

4x -1 = 4(14) -1 = 55

The measures of the angles are ...

∠K = ∠M = 55°
