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

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

$h=6\ units$

Help I don't know what to choose

Lunna [17]

Answer:

Step-by-step explanation:

We know a triangle adds up to 180 so:

75+36+ ? = 180

111+ ? =180

? = 69

To find out x, we know that a straight line adds up to 180 so again:

x +69 = 180

x = 111

Lelechka [254]

Try this option:

the final price of the first machine after discount is:

(1-0.3)*495=346.5$;

the final price of the second machine after all the discount is:

(1-(0.2+0.2*0.1))*495=386.1$.

Short explanation: the additional 10% off is 2% of the initial price for the second machine; the final discount of the second machine is 22%.

Using A=Pe^rt solve A=1,240,000 r=8% t=30 years what is P?

muminat

Answer:

P= 112,490.26207887

P= 112,490 (it should be a whole number for oliy represents the number of humans)

Step-by-step explanation:

1,240,000 = P e^(0.08×30)

________ ____________

e^(0.08×30) e^(0.08×30)

P = 112,490.26207887

1,240,000 = P e^(0.08×30)

____________ ____________

11.0231763806 11.0231763806

P = 112,490.26207887
