Art [367]

Answer:

$10.30

Step-by-step explanation:

X = 49.95 - (24.65 + 15)

x = 49.95 - 39.65

x = 10.30

Answer:

The answer to your question is below

Step-by-step explanation:

Use trigonometric functions to find x

13. cos 40 = 5/x

x = 5 / cos 40

x = 5 / 0.766

x = 6.5

14. tan 25 = x/9

x = 9tan 25

x = 9(0.466)

x = 4.2

15.- cos 65 = x/12

x = 12 cos 65

x = 12 (0.423)

x = 5.1

16.- sin 32 = 15/x

x = 15 / sin 32

x = 15 / 0.53

x = 28.3

17.- tan 55 = 20 / x

x = 20 / tan 55

x = 20 / 1.42

x = 14

18.- sin31 = x / 18

x = 18 sin 31

x = 18 (0.52)

x = 9.3

PLEASE HELP WITH GEOMETRY IM STUCK!?}

Ilya [14]

Answer:

13.8

Step-by-step explanation:

Recall the trigonometric ratios

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now lets look back at the question

We are given an angle and its adjacent side length (11) and we need to find the hypotenuse

The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x

( remember that cosine = adjacent over hypotenuse )

$cos(37)=\frac{11}{x}$

step 1 multiply each side by x

$cos(37)*x=xcos(37)\\\frac{11}{x} *x=11$

now we have $xcos(37)=11$

step 2 divide each side by cos(37)

$\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\$

we're left with x = 13.77439

Our last step would be to round to the nearest tenth

We would get that the answer is 13.8
