A guy-wire is attached to a pole for support. If the angle of elevation to the pole is 67° and the wire is attached to the groun

d at a point 137 feet from the base of the pole, what is the length of the guy wire (round to 2 decimal places)?

You have to go at this in a round-about fashion...by finding the length of the leg across from the 67 degree angle.  This is found by using the tangent ratio...Tan(67)=x/137; x=137tan(67) = 322.8. Now you can use this in one of two ways: use Pythagorean's Theorem to find the length of the hypotenuse OR you could use the sin67=322.8/x.  Up to you. Either way, make sure you have your calculator in degree mode!

PLEASE HELP!!!!<br><br> Use the table below to match the slopes to the lines.
skelet666 [1.2K]

Answer: Check out the filled out chart below.

Row 1:  1/4, 1/4,  -4

Row 2: -2, -2, 1/2

Row 3: 3, 3, -1/3

=========================================

Explanation:

Parallel lines have equal slopes. So if the original line has slope 1/4, then any parallel line will also have slope 1/4. The only thing different is the y intercept.

Perpendicular slopes multiply to -1 assuming neither line is vertical. For row 1, the perpendicular slope is -4 which multiplies with the original slope 1/4 to get -1.

Put another way, the perpendicular slope is the negative reciprocal of the original slope. For row 2, the perpendicular slope is 1/2 because we flip the fraction and the sign for the original slope -2 = -2/1

Given that (Triangle)MNO is similar to (Triangle)RST, determine the perimeter of (Triangle)RST.
blsea [12.9K]

Answer:

C

Step-by-step explanation:

Given that the 2 triangles are similar then the ratios of corresponding sides are equal.

This enables RT to be found, that is

\frac{4}6} = \frac{10}{RT} ( cross- multiply )

4RT = 60 ( divide both sides by 4 )

RT = 15

Hence

perimeter of ΔRST = 6 + 12 + 15 = 33 units
