Answer:

  54.5°

Step-by-step explanation:

You know that in a right triangle, the sine of an angle is given by ...

  Sin = Opposite/Hypotenuse

  sin(D) = EF/ED = 57/70

The inverse sine function is used to find the angle:

  ∠D = arcsin(57/70)

  ∠D ≈ 54.5°

13 + 2v - 8 + 6 > -7 - v please simplify and explain IN ONLY NUMBERS NO WORDS
insens350 [35]

Answer:

v > - 6

Step-by-step explanation:

13 + 2v - 8 + 6 > -7 - v (calculate the sum of difference)

= 11 + 2v>-7-v (move variable to the left-hand side and change its sign and move constant to the right-hand side and change its sign)

= 2v + v > - 7 - 11 (collect like items and calculate the difference)

= 3v>-18 (divide both sides of the inequality by 3)

=v > - 6

*in parentheses is written what to do to get the next number*
