Answer:

23.78 cm

Step-by-step explanation:

Since, We know that,

In a right angle triangle,

$cos \theta=\frac{B}{H}$

Where, B represents base adjacent to $\theta$

H represents the hypotenuse adjacent to $\theta$

Thus, by the given diagram,

$cos 18^{\circ}=\frac{x}{25}$

$\implies x = 25\times cos 18^{\circ}=23.7764129074\approx 23.78\text{ cm}$

Hence, Last option is correct.

In a company, 85% of the workers are men. If 360 people work for the company who aren't men, how many workers are there in

geniusboy [140]

If 85% are men, then (100 - 85), 15% are not men

so, 15% are not men which means that 15% are 360 = 15% of x = 360

(x = total no. of workers)

so, x = 360 × $\frac{100}{15}$ = 2400

The total number of people = 2400

What is the length of the hypotenuse?

erma4kov [3.2K]

Answer:

The answer is c = 17 feet

Step-by-step explanation:

The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).

a = 8 feet

b = 15 feet

a^2 = 8 * 8 = 64

b^2 = 15 * 15 = 225

The next step is to add: 64 + 225 = 289

But we need to remember to square root 289 because we squared a and b.

The square root of 289 equals 17

c = 17 feet

The ratio of blue jays to Robin's was 6 to 7. If there were 84 Robins, how many blue jays were there?

Paul [167]

Answer:

Step-by-step explanation:

Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.

6 to 7 can also be express as 6/7

Thus, we can set up a proportion

6/7 = x/84

Now, we have to solve for x

x = 72

Hence, if there were 84 robin there would be 72 blue jays.

Find the width of rectangle which has perimeter of 24 cm and length is 8 cm. *

MakcuM [25]

Answer:

Breadth is 4cm

Step-by-step explanation:

Perimeter = 24cm

Length= 8cm

let the breadth be x

Perimeter = 2(l+b)

24 = 2(8+x)

24 = 16+2x

24-16 = 2x

8 = 2x

8÷2 = x

4 = x

Therefore, breadth is 4cm
