Step-by-step explanation:

< A = 4x

< B = 3x - 3°

<C = 5x + 3°

Solving for x

< A +<B + <C = 180° {Being sum of angles of triangle }

4x + 3x - 3 ° + 5x + 3° = 180°

12x = 180°

x = 180° / 12

x = 15°

Measure of <A

= 4 * 15°

= 60°

Measure of < B

= 3 * 15° - 3°

= 42°

Measure of < C

= 5* 15° + 3°

= 78°

Hope it will help :)❤

<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] cosθ = adjacent over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

Angle θ = <em>x</em>

Adjacent Leg = 5.8

Hypotenuse = 7.3

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Cosine]:                                                                    \displaystyle cosx^\circ = \frac{5.8}{7.3}
  2. [Fraction] Divide:                                                                                             \displaystyle cosx^\circ = 0.794521
  3. [Equality Property] Trig inverse:                                                                    \displaystyle x^\circ = cos^{-1}(0.794521)
  4. Evaluate trig inverse:                                                                                      \displaystyle x = 37.39^\circ
  5. Round:                                                                                                             \displaystyle x \approx 37.4^\circ
