Solve for x.<br><br> −34(x+2)=6
diamong [38]
<span>−34(x+2)=6
Use distributive property
-34x - 68=6
Add 68 to both sides
-34x=74
Divide -34 on both sides
Final Answer: x = -74/34 or -2 6/34 *Both answers are equivalent to each other.</span>

The answer written in the box is not correct. HELP PLEASE IF YOU KNOW THIS TRIGONOMETRY/PYTHAGORAS QUESTION
den301095 [7]

Answer:

18.55

Step-by-step explanation:

Step One

Find AC

<em><u>Formula</u></em>

a^2 + b^2 = c^2

<em><u>Givens</u></em>

  • a = 70
  • b = 50
  • c = AC

<em><u>Solution</u></em>

  • AC^2 = 70^2 + 50^2                Substitute into Pythagoras
  • AC^2 = 4900 + 2500               Expand  
  • AC^2 = 7400                             combine
  • AC = sqrt(7400)                         Take the square root of both sides.
  • AC = 86.02

Step Two

Find FC

<em><u>Givens</u></em>

  • <BCF = 30o                                          Given
  • BC    =  50                                            Given
  • FC =                                                      Find

<em><u>Formula</u></em>

Tan(30) = FC/50

<em><u>Solution</u></em>

FC = 50 * tan(30)

FC = 28.87

Step Three

Find <FAC

FC = 28.87

AC = 86.02

Tan(<FAC) = FC / AC

Tan(<FAC) = 28.87/86.02

Tan(<FAC) = 0.33558

<FAC = Tan-1(0.33558)

<FAC = 18.55 which is just about what you got.
