A 30° 60° 90° triangle is shown below. Find the length of the side labeled y.

bulgar [2K]

Answer:

Part 1) $y=3\ units$

Part 2) The length of the hypotenuse is 6 units

Step-by-step explanation:

Part 1) we know that

In the right triangle of the figure

$sin(60^o)=\frac{y}{2\sqrt{3}}$ ----> by SOH (opposite side divided by the hypotenuse)

solve for y

$y=sin(60^o)2\sqrt{3}$

Remember that

$sin(60^o)=\frac{\sqrt{3}}{2}$

substitute

$y=(\frac{\sqrt{3}}{2})2\sqrt{3}$

$y=3\ units$

Part 2)

Let

h ----> the length of the hypotenuse

we know that

In the right triangle of the figure

$sin(45^o)=\frac{3\sqrt{2}}{h}$ ----> by SOH (opposite side divided by the hypotenuse)

$h=\frac{3\sqrt{2}}{sin(45^o)}$

Remember that

$sin(45^o)=\frac{\sqrt{2}}{2}$

substitute

$h=3\sqrt{2}:\frac{\sqrt{2}}{2}$

$h=6\ units$

Urgent please help with finding rate of change

boyakko [2]

When working with functions (of all types), the average rate of change is expressed using function notation:

$\dfrac{f(b)-f(a)}{b-a}.$

For the interval from x=7 to x=8,

1. find f(7) and f(8):

$f(7)=729\cdot 3=2187;$
$f(8)=2187\cdot 3=6561;$

2. use given formula:

$\dfrac{f(8)-f(7)}{8-7}=\dfrac{6561-2187}{8-7}=4374.$

Answer: the average rate of change for the interval from x=7 to x=8 is 4374.

A board is leaning against a vertical wall, The board makes a 62 degree angle with the ground and touches the wall at a point th

Korvikt [17]

Angle A = 62°
Angle B = 90°
Side a = 45
The length of the board is side b

Use the Law of Sines to find side b.
b / sin(B) = a / sin(A)
b / sin(90°) = 45 / sin(62°)
b = (sin(90°) x 45) / sin(62°)
b = 50.966

Rounded to the nearest inch is 51 inches.

Hope this helps!
