21) 2x+16=2*23+16=46+16=62
3x-7=3*23-7=69-7=62,
so we can see that 2x+16=3x-7, that means that lines are parallel , because the corresponding angles are equal. 

problem with triangle
130+a=180, a=50,

50+8x+2x=180
50+10x=180
10x=130
x=13

8x+b=180
b=180-8x=180-8*13=76

2x+c=180
c=180-2x
c=180-2*13= 154

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use trig to find the missing angle.

<u>Step 2: Identify Variables</u>

<em>POV from angle x</em>

Angle = <em>x</em>

Adjacent = 16

Hypotenuse = 27

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute:                    cosx° = 16/27
  2. Inverse:                         x° = cos⁻¹(16/27)
  3. Evaluate:                       x = 53.6588°
