ss7ja [257]

Answer:

23) option c

    JL ≈ 9.3

25) option c

      y ≈ 9.6

Step-by-step explanation:

<h3>25)</h3>

Given in the question that,

cos(21°) = 9 / y

y = 9/cos(21°)

y = 9.64

y ≈ 9.6(nearest tenth)

<h3>23)</h3>

Given in the question that the hypotenuse of right angle triangle = 12

To find,

height of the right angle triangle

angle k = 39°

so by using trigonometry identity

cos(39) = opp/hypo

cos(39) = JL / KL

JL = cos(39)(12)

JL = 9.32

JL ≈ 9.3

What is x in .80x+30=1.20x+14
Sonja [21]

Answer:

x =  40

Step-by-step explanation:

.80x + 30 = 1.20x + 14

<u>-.80x        = -.80x        </u>

          30 = .4x  + 14

        <u>  -14 =         -14</u>

           16 = .4x

            16/.4  = .4/.4x

              40    =  x
