The required exact value of tan(67.5°) is -2 + √(2).

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,
The exact value of tan(67.5°) can be found using the half-angle identity for the tangent, which states that:

tan(x/2) = (1 - cos(x)) / sin(x)

We can use this identity with x = 135 degrees since 67.5 degrees is half of 135 degrees. So:

tan(67.5°) = tan(135°/2) = (1 - cos(135°)) / sin(135°)

We can then use the following exact values:

cos(135°) = -√(2)/2

sin(135°) = -√(2)/2

Substituting these values, we get:

tan(67.5°) = (1 + √(2)/2) / (-√(2)/2)

Rationalizing the denominator, we get:

tan(67.5°) = -2 + √(2)

Therefore, the exact value of tan(67.5°) is -2 + √(2).

Answer:

y = 2x + 14

Step-by-step explanation:

Equation in slope intercept form:

y = mx + c

From the scenario above ;

y = total miles = 30

Average mile gain per week = slope (m) = 2

Number of weeks (x) = 8

We can obtain intercept, c :

30 = 2(8) + c

30 = 16 + c

30 - 16 = c

14 = c

Hence,

Equation goes thus ;

y = 2x + 14

Answer:

Length of the bold arc = 72.63 ft

Step-by-step explanation:

Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = angle subtended by the arc at the center

r = Radius of the circle

Since, angle subtended by the bold arc at the center = 360 - 73

                                                                                         = 287°

And radius of the circle 'r' = 14.5 ft

By substituting these values in the formula,

Length of the bold arc = [tex]\frac{287}{360}\times (2\pi)(14.5)[/tex]

                                     = 72.632

                                     ≈ 72.63 ft

Therefore, length of the bold arc = 72.63 ft

Answer:

y= -3/2x+9

Step-by-step explanation:

Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9

Answer:

35.09

Step-by-step explanation:

From the question given above, the following data were:

Opposite = 12

Hypothenus = X

Angle θ = 20 °

The value of x can be obtained by using sine ratio as illustrated below:

Sine θ = Opposite / Hypothenus

Sine 20 = 12 / X

0.342 = 12 / X

Cross multiply

0.342 × X = 12

Divide both side by 0.342

X = 12 / 0.342

X = 35.09

Thus, the value of X is 35.09
