Mathematics
1 answer:
tatyana61 [14]3 years ago
5 0

Answer:

x = 4

Step-by-step explanation:

x + 4(x+5) = 40 (Given)

x + 4x + 20 = 40 (Distribute the 4 into the x and 5)

5x + 20 = 40 (Add like terms)

5x = 20 (Subtract 20 on both sides)

x = 4 (Divide 5 on both sides)

The missing justification in the proof is
<span>B) Substitution property of equality

The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.

Answer:

56.6 °

For a RIGHT triangle    cos (x ) = adjacent leg / hypotenuse

                                      cos (x) = 4.4 / 8

                                            arc  cos (4.4/8) = 56.63 °  = ~ 56.6°
