Use the properties of 30-60-90 and 45-45-90 triangles to solve for x in each of the problems below. Then decode the secret messa
Flauer [41]

With the help of trigonometric function, the above problems have been calculated. See explanation below.

<h3>What are Trigonometric functions?</h3>

The term "trigonometric function" refers to functions that are periodic in nature and that shed light on how a right-angled triangle's angles and sides relate to one another.

The solutions to x in the respective problems is given as follows:

1) x = 5 /Sin(30°)

x = 10

!) Sin(45°) = 4/x

x = 4/sin(45°)

x = 4√2

I) Cos(45°) = √3 / x

x = √3 / Cos(45°)

x = √6

E) Tan(60°)

= (3√3) / x

x = (3√3) / 3

W) In trigonometry, every right-triangle that is isosceles in nature, the angle made by the legs and the hypotenuse will always equal 45°.

x = 45°

N) x² + x² = (7√2)²

x = 7

V) Tan(60°) = 7 / x

x = 7√3/3

K) x² + x² = (9)²

x = 9/√2

Y) Sin(60°) = 7√3/x

x = 14

M) Sin(30°) = x/11

x = 11/2

T) Sin(45°) = x/√10

x = √5

A) x + 2x + 90° = 180°

x = 30°

O) Sin(45°) = √2 / x

x = 2

R) Tan(30°) = x / 4

x = 4/√3

= 4√3 / 3

S) Sin(60°) = x / (10/3)

x = (5√3) / 3

A garden snail traveled 1⁄40 of a mile in 1⁄2 an hour. What was the speed of the snail?
abruzzese [7]
There are several information's of immense importance already given in the question. Based on those information's the answer to the question can be easily deduced.
The total distance that has been traveled by the garden snail in question = 1/40 mile
Time taken by the garden snail to travel the distance given in question = 1/2 hour.
Then
Speed of the snail = Distance traveled/ Time taken
                             = (1/40)/(1/2) miles per hour
                             = 2/40 miles per hour
                             = 1/20 miles per hour
So the speed of the garden snail as can be seen from the above deduction is 1/20 miles per hour. I hope the procedure is simple enough for you to understand.
