Use trigonometry to find the missing side. Round your answer to the nearest tenth (one decimal place)

Alchen [17]

Given:

A figure of a right triangle.

To find:

The missing side by using the trigonometric ratios.

Solution:

In a right angle triangle,

$\cos \theta=\dfrac{Adjacent}{Hypotenuse}$

In triangle ABC,

$\cos A=\dfrac{AC}{AB}$

$\cos (31^\circ)=\dfrac{b}{270}$

$0.857=\dfrac{b}{270}$

Multiply both sides by 270.

$0.857\times 270=b$

$231.39=b$

$b\approx 231.4$

Therefore, the missing side length is b=231.4 inches.

Find the value of expression - 17x-19xpwer4 - 21x power 2,when x=3<br><br>

Marrrta [24]

Answer:

$-17x - 19x^4 - 21x^2 = -1779$ when $x = 3$

Step-by-step explanation:

Given

$-17x - 19x^4 - 21x^2$

$x = 3$

Required

Solve

Substitute 3 for x in $-17x - 19x^4 - 21x^2$

$-17x - 19x^4 - 21x^2 = -17*3 - 19*3^4 - 21*3^2$

Evaluate all exponents

$-17x - 19x^4 - 21x^2 = -17*3 - 19*81 - 21*9$

$-17x - 19x^4 - 21x^2 = -51 - 1539- 189$

$-17x - 19x^4 - 21x^2 = -1779$

Write an expression for the area of the shaded region in its simplest form. Show all of your steps.

patriot [66]

The area of the shaded region will be the area of the rectangle minus the area of the white square inside of it:

((x+10)(2x+5)) - ((x+1)(x+1))

First, FOIL both of the areas separately:

(2x^2 + 5x + 20x + 50) - (x^2 + x + x + 1)

Simplify within the parentheses by adding like terms:

(2x^2 + 25x + 50) - (x^2 + 2x + 1)

Now, subtract one equation from the other:

2x^2 + 25x + 50
-x^2 - 2x - 1
= x^2 + 23x + 49

This will be the equation for the area.
