Step-by-step explanation:

Here,

Window is in the rectangular shape.
Measure of its one diagonal is 13 feet.

According to the properties of rectangle,

→ Diagonals of a rectangle are equal.

So, here the length of other diagonal will be 13 feet too.

Sam is at the top of a tower and will ride down a zip line to a lower tower. The total vertical drop of the zip line is 40 ft. T

jek_recluse [69]

Answer:

149.30ft

Step-by-step explanation:

Since the vertical distance between the two tower = 40ft

The angle of elevation from the lower tower to te higher tower = 15°

The horizontal distance between the two towers = x

Assuming the angle of elevation and the distance between the two towers makes a right angle triangle, we can use SOHCAHTOA and determine which one would be suitable to find x.

Check attached document for better illustration of the triangle.

Tanθ = opposite / adjacent

Opposite = 40

θ = 15°

Adjacent = x

Tan15 = 40 / x

0.2679 = 40 / x

X = 40 / 0.2679

X = 149.30ft

The horizontal distance between the two towers is 149.30ft

In a village the number number of houses and flats are in a a ration 9:5

ki77a [65]

Answer:

180 houses

Step-by-step explanation:

The 3 part of the ratio 10 : 3 represents 30 bungalows, thus

30 ÷ 3 = 10 ← value of 1 part of the ratio

10 parts = 10 × 10 = 100 ← number of flats

The 5 part of the ratio 9 : 5 represents 100 flats, thus

100 ÷ 5 = 20 ← value of 1 part of the ratio, then

9 parts = 9 × 20 = 180 ← number of houses

Solve for the missing angle. Round to the nearest hundredth. 18 ? 13 ? = degrees

skad [1K]

Answer:

$\theta \:=43.76^{\circ \:\:}$

Step-by-step explanation:

The right triangle has the hypotenuse = 18

Let 'Ф' be the missing angle

we know that

cos Ф = adjacent/hypotenuse

Here,

The adjacent to Ф = 13

The hypotenuse = 18

cos Ф = adjacent/hypotenuse

$cos\:\theta \:=\frac{13}{18}$

$\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)$

$=43.76^{\circ \:}$

Therefore, the missing angle is:

$\theta \:=43.76^{\circ \:\:}$
