For a right triangle, we have he advantage of using the trigonometric functions like cosine and sine.

If you use cosine function:
cos45 = adjacent/hypotenuse
cos 45 = b/c
c = b/cos 45

If you use sine function:
sin 45 = opposite/hypotenuse
sin 45 = a/c
c = a/sin45

From the choices, the answer is <span>b over cos 45 degrees</span>

Let the required number be x, then 10 + x/6 = 5
x/6 = 5 - 10 = -5
x = 6 x -5 = -30
x = -30

A boy 1.5 m tall can just see the sun over a wall 71.5 m high which is

igomit [66]

Answer:

C. 45 degree angle

Step-by-step explanation:

let AB be the height of the wall and CD be the height of boy

with BC as distance between them.

we have AE = AB-BE = 3.64-1.54 = 2.1m

and ED = BC = 2.1m

in triangle AED, we have

tanФ = P/B = 2.1/2.1

tanФ = 1

∴ Ф = 45°

Hence the sun is elevated at an angle of 45 °.

Which feature distinguishes mathematics from the other science ? Justify your answer.

andreyandreev [35.5K]

The main difference between mathematics and other sciences is that mathematics deals with rational models, in which they apply logical implications in axioms they assume. On the other hand, science uses these axioms and models to describe a certain natural phenomenon.
