\cos (\theta) =  \dfrac{adj}{hyp}

\cos (39) =  \dfrac{x}{17}

x= 17\cos (39)

x= 13.2 \text { m}

So you would do cos(39) times 17.
x= cos(39)*17
x= .777*17
x= 13.21
And since it says round to the nearest tenth, you would put 13.2 m for the answer.

I need help on this question
kherson [118]

Answer:

A

Step-by-step explanation:

Just put x = 80 and y = 210 into the equation...

or put x = 40, y = 90.

A:

210 - 90 = 3(80-40)

120 = 120√

B:

210 + 90 = 3(80+40)

300 = 360×

C:

210 - 90 = 2.6(80-40)

120 = 104×

D:

210 + 90 = 2.6(80+40)

300 = 312×
