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

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

$h=6\ units$

A 20-meter long cable is used to support a telephone pole, holding the pole to make the pole perpendicular to the ground. If the

natka813 [3]

Answer:

17.32 meters

Step-by-step explanation:

We realize the cable is the hypotenuse and then that height would be the new side, the measurement would not change once hypotenuse is found.

60 deg is the lower angle as it meets the ground base.

Sin (60) = 0.8660254038 x 20 = 17.32m

0.86 reduction = a

We use Sin (60) = a a x 20 to find the pole as above.

We use Tan (60) x base to find 20m to check hypotenuse if base was given = length of floor x tan(60) etc.
