8 ABC please trig assignment

Using equivalent angles, the solutions are given as follows:

a) $x = \frac{15\pi}{23}$ .

b) $x = \frac{9\pi}{62}, x = \frac{53\pi}{62}$ .

c) $x = \frac{3\pi}{8}, \frac{11\pi}{8}$

<h3>What are equivalent angles?</h3>

Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant.

For item a, we have to find the equivalent angle on the 2nd quadrant, where the sine is also positive.

Hence:

$\pi - \frac{8\pi}{23} = \frac{23\pi}{23} - \frac{8\pi}{23} = \frac{15\pi}{23}$

Hence $x = \frac{15\pi}{23}$ .

For item b, if two angles are complementary, the sine of one is the cosine of the other.

Complementary angles add to 90º = 0.5pi, hence:

$x + \frac{11\pi}{31} = \frac{\pi}{2}$

$x = \frac{31\pi}{62} - \frac{22\pi}{62}$

$x = \frac{9\pi}{62}$

The equivalent angle on the second quadrant is:

$\pi - \frac{9\pi}{62} = \frac{62\pi}{62} - \frac{9\pi}{62} = \frac{53\pi}{62}$

Hence the solutions are:

$x = \frac{9\pi}{62}, x = \frac{53\pi}{62}$

For item c, the angles are also complementary, hence:

$x + \frac{\pi}{8} = \frac{\pi}{2}$

$x = \frac{4\pi}{8} - \frac{\pi}{8}$

$x = \frac{3\pi}{8}$

The tangent is also positive on the third quadrant, hence the equivalent angle is:

$x = \pi + \frac{3\pi}{8} = \frac{8\pi}{8} + \frac{3\pi}{8} = \frac{11\pi}{8}$

Hence the solutions are:

$x = \frac{3\pi}{8}, \frac{11\pi}{8}$

Angelique Calculated the slope of a line that passed through points (-5,4) and (2,-3) her work is shown below. identify her erro

SOVA2 [1]

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 5, 4 ) and (x₂, y₂ ) = (2, - 3 )

m = $\frac{-3-4}{2-(-5)}$

Her error was subtracting 5 from 2 instead of - 5 from 2

m = $\frac{-7}{2+5}$ = $\frac{-7}{7}$ = - 1 ← corrected solution

The length of a rectangle is represented by (2x2−5x+5)cm and the width is represented by (x2+4x−3)cm. What is the representation

Katarina [22]

Answer: $6x^2-2x+4$

Step-by-step explanation:

Given

The length of a rectangle is given by

$l=2x^2-5x+5$

and the breadth is given by

$w=x^2+4x-3$

Perimeter is the sum of the sides of rectangle

$\therefore \text{Perimeter P= }2(2x^2-5x+5+x^2+4x-3)\\\Rightarrow P=2(3x^2-5x+4x+5-3)\\\Rightarrow P=2(3x^2-x+2)\\\Rightarrow P=6x^2-2x+4$

Thus, the perimeter is given by $6x^2-2x+4$ .
