Answer:

x = -9

Step-by-step explanation:

Segment NL is twice the length of midsegment WV.

2WV = NL

2(x+15) = x+21

2x +30 = x +21 . . . . simplify

x = -9 . . . . . . . . . . . . add -30-x

_____

<em>Additional comment</em>

This value of x means the other segments are ...

MN = 12

WV = 6

NL = 12

PLEASE HELP!! if sec x=5/3 what is the value of b? NL=20 LM=3b angle of L is x degrees.

Readme [11.4K]

Answer:

a. b=4

Step-by-step explanation:

$\sec \theta =\dfrac{1}{\cos \theta} = \dfrac{Hypotenuse}{Adjacent}$

From the attached triangle drawn below:

NL=20, LM=3b, $\angle L=x^\circ$

$\sec x =\dfrac{20}{3b}$

Since we are told that:

$\sec x =\dfrac{5}{3}\\$Then:\\\dfrac{20}{3b} =\dfrac{5}{3}\\$Cross multiply\\5 \times 3b =20 \times 3\\15b=60\\$Divide both sides by 15\\15b \div 15 =60 \div 15\\b=4$

The correct option is A.

Help on precal, what are the answers?

Sloan [31]

1) cscΘ = - 2

=>

1
------ = - 2
sinΘ

=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant

=> Θ = 180° + 30° = 210°

and Θ = 360° + 30° = 330°

2) tan Θ = √3

=> Θ = 60° and Θ = 180° + 60° = 240°
