Hypotenuse = 22*sq root (2)
I'm guessing you need to know the length of the triangle legs?
The triangle leg of a 45 45 90 triangle = hypotenuse / sq root (2)
triangle leg= 22* sq root (2) / sq root (2)
triangle leg=22

Answer:

22units

Step-by-step explanation:

Using the SOH CAH TOA method to solve the problem since the triangle is a 45°-45°-90° triangle which is a right angled triangle due to the presence of 90° as one or the angles.

If one of the sides is 22√2units,

Using SOH which states;

sin(theta) = Opposite/Hypotenuse

theta =45° (the angle facing one of the acute angle in the triangle)

Opposite side = 22√2

Substituting the datas into the formula we will have;

Sin 45° = 22√2/Hyp

1/√2 = (22√2)/Hyp

Cross multiplying;

Hypotenuse = √2×22/√2

Hypotenuse = 22units

Answer:

14) 21.136505024965 m

15) 43.076759215619 km

Step-by-step explanation:

14)

let h be the height of the lighthouse:

tan(41.3) = 18.7/h

Then

h = 18.7÷tan(41.5)

= 21.136505024965 m

………………………………………

15)

90-71.4 =18.6

Let s be the distance that the plane flew

towards the south:

tan(90 - 71.4) = s/128

Then

tan(18.6) = s/128

Then

s = tan(18.6)×128

= 43.076759215619 km

taurus [48]

Answer:

This is an experiment with blocking ( B )

Step-by-step explanation:

The best way to describe this experiment is an experiment with blocking this is because the Type of surface where the tape is been tested can be considered a blocking variable while the weights can be considered as treatments

A blocking variable is a variable used in experiment which is not of primary interest to the experiment observer ( I.e. The tape is supposed to hold on all types of surfaces and not just on Aluminum and wood surface )

sergey [27]

Answer:

$\dfrac{3}{14}$

Step-by-step explanation:

The even number of minus signs means the product will be positive. A factor of 3 can be removed to simplify the product. As usual, the numerator of the product is the product of numerators, and the denominator of the product is the product of denominators.

$-\dfrac{1}{6} \times \left(-\dfrac{9}{7}\right)=\dfrac{1\cdot 9}{6\cdot 7}=\dfrac{3\cdot 3}{3\cdot 14}=\boxed{\dfrac{3}{14}}$

kramer

Answer:

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.

$\frac{\text{Time}}{\text{Array of elements}}=\frac{4}{8}$

$\frac{t}{24}=\frac{4}{8}$

$\frac{t}{24}\cdot 24=\frac{4}{8}\cdot 24$

$t=\frac{4}{1}\cdot 3$

$t=12$

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.
