Margarita [4]3 years ago
6 0

Answer:

see below

Step-by-step explanation:

1. opposite of cosine  

Cosine = opposite/hypotenuse

There is a reciprocal of cosine called secant  = hypotenuse / opposite

2.    We want to find the height of the tower, y

tan C = y/ x

tan 60 = y/15

Multiply each side by 15

15 tan 60 =y/15 *15

15 tan 60 =y

25.98076211 = y

The height is 25.98076211 m or approximately 26 m

3.  The angle to the nearest degree

tan ? = opposite/ adjacent

tan ? = 27/38

Taking the inverse

tan^-1 (tan ?) = tan ^-1 (27/38)

? =35.39479584

To the nearest degree = 35

Answer:

secant

≈ 26 m

≈ 35°

Step-by-step explanation:

QUESTION 1

Opposite of cosine ⇒ secant  = hypotenuse / opposite leg

QUESTION 2

Height of the tower

tan 60 = h/ 15

h= 15 tan 60 ≈ 26 m

QUESTION 2

tan x = 27/38

x ≈ 35°

Complete the mixed number equation that is represented by the area model
lubasha [3.4K]

From the given data, it is clear that the first area model represents the fraction \frac{1}{2} .

From the second area model,

Total number of regions = 6

Number of shaded regions = 2

The fraction represented by the model = \frac{2}{6}= \frac{1}{3} .

Let's complete the expression.

\frac{1}{2} (\frac{1}{3} )=\frac{1}{6}

What is the product of the binomials below?
Otrada [13]

Answer:

The correct answer is 8x^2+28x+20.

Step-by-step explanation:

(2x+5)(4x+4)

Multiply the first bracket with each element of second bracket:

=4x(2x+5)+4(2x+5)

=8x^2+20x+8x+20

Now solve the like terms:

=8x^2+28x+20

Thus the correct answer is 8x^2+28x+20....

What is the diagonal of a right triangle
bekas [8.4K]

Answer:

diagonal of a polygon is a line from a vertex to a non-adjacent vertex. So a triangle, the simplest polygon, has no diagonals. You cannot draw a line from one interior angle to any other interior angle that is not also a side of the triangle.

Step-by-step explanation:

To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse. Then solve for c
