Maths question trigonometry help pleassssee

r-ruslan [8.4K]

Answer:

x=4.5

Step-by-step explanation:

Using sohcahtoa we know tangent is equal to (length of side opposite to the angle ) / (lenth of side adjacent to the angle)

therefore: tan (theta) = (x-3) / (x) = 1 / 3

now cross multiply

3(x-3) = x

now solve for x

3x - 9 = x

-9= -2x

x= 4.5

This is my hardest one so far. plz help.

x - 27 = 62 → ( add 27 to both sides )

x - 27 + 27 = 62 + 27

x = 89

drag first box then box with x = 89

Bob is driving along a straight and level road toward a mountain. At some point on his trip, he measures the angle of elevation

DerKrebs [107]

Answer:

Option A.

Step-by-step explanation:

Distance between Bob and the center of the mountain at the base = 19,427.5 ft.

Angle of elevation to the top of the mountain = 25°11'

We know that

1 degree = 60 minutes

1/60 degree = 1 minute

$25^{\circ}11'=25^{\circ}+\frac{11}{60}{\circ}\Rightarrow 25^{\circ}+0.183^{\circ}=25.183^{\circ}$

Let the height of the mountain be h.

In a right angled triangle

$\tan\theta = \frac{opposite}{adjacent}$

$\tan(25.183^{\circ}) = \frac{h}{19427.5}$

$\tan(25.183^{\circ})\times 19427.5 = h$

$h=0.4702\times 19427.5$

$h=9134.8105$

$h\approx 9135$

Therefore, the height of the mountain to the nearest foot 9135. Option A is correct.
