answer to the nearest tenth.

9514 1404 393

Step-by-step explanation:

The missing side is found using the Pythagorean theorem:

  X = √(37^2 -22^2) = √885 ≈ 29.7 . . . feet

The missing angle is found using the cosine relation:

  Cos = Adjacent/Hypotenuse

  cos(x) = 22/37

  x = arccos(22/37) ≈ 53.5°

The posted question asks for side length; the picture asks for angle.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
