    Step-by-step explanation:

    Hope this helped.

    I hate asking for things but May I have brainliest I need to rank up.

  2. 9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

    10) y = 14 x = √147 or 12.12435565

    11) x = 4.8

    12) x = 4.2

    13) x = 9.3

    14) pq: 13.2

    qr : 17.6

    angle p: 53º

    15) angle c: 54.3º

    angle a: 35.7º

    16) h = 21040

    v = 1841

    step-by-step explanation:

    10) 7/sin(30) = 14 = y

    7^2 + b^2 = 14^2

    49 + b^2 = 196

    b^2 = 196 - 49

    √b^2 = √147

    x = √147

    11) cos(70) x 14 = 4.788282007

    x = 4.8

    12) tan(25) x 9 = 4.196768923

    x = 4.2

    13) sin(31) x 18 = 9.270685348

    x = 9.3

    14) pq: sin(37) x 22 = 13.23993051

    pq: 13.2

    qr: cos(37) x 22 = 17.56998122

    qr : 17.6

    angle p: 180 - (37 + 90) = 53º

    15) cos-1(7/12) = 54.31466529

    angle c: 54.3º

    angle a: 180 - (90 + 54.31466529) = 35.68533471

    angle a: 35.7º

    16) 4 x 5280 = 21120

    cos(5) x 21120

    h = 21039.63202

    h = 21040

    sin(5) x 21120

    v = 1840.729287

    v = 1841

    [tex]Lots of points! show all of your work! i need #9-#14 and 12 + 16![/tex]
