Solve for x <br> Need help asap
vlabodo [156]

Answer:

x=55

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of 2x+6 corresponds with the angle marked as x+9. Therefore, its measure must also be x+9.

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

2x+6+x+9=180

Combine like terms:

3x+15=180

Subtract 15 from both sides:

3x=165

Divide both sides by 3:

x=\frac{165}{3}=\boxed{55}

If tan0=-3/4 and 0 is in quadrant IV, cos20= (33/25, -17/25, 32/25, 7/25, 24/25?) and tan20= (24/7, -24/7, 7/25, -7/25, 13/7, -1
Oksana_A [137]

Answer:

  • cos(2θ) = 7/25
  • tan(2θ) = -24/7

Step-by-step explanation:

Sometimes, it is easiest to let a calculator do the work. (See below)

__

The magnitude of the tangent is less than 1, so the reference angle will be less than 45°. Then double the angle will be less than 90°, so will remain in the 4th quadrant, where the cosine is positive and the tangent is negative.

You can also use the identities ...

  cos(2θ) = (1 -tan(θ)²)/(1 +tan(θ)²)

  cos(2θ) = (1 -(-3/4)²)/(1 +(-3/4)²) = ((16-9)/16)/((16+9)/16)

  cos(2θ) = 7/25

__

  tan(2θ) = 2tan(θ)/(1 -tan(θ)²) = 2(-3/4)/((16-9/16) = (-6/4)(16/7)

  tan(2θ) = -24/7
