Answer:

\large\boxed{|x+7|\geq2}

Step-by-step explanation:

Look at the picture.

|x-a|\geq b\\\\a=\dfrac{-9+(-5)}{2}=\dfrac{-14}{2}=-7\\\\b=-9-(-7)=-9+7=-2\\b=-5-(-7)=-5+7=2\\\\|x-(-7)|\geq2\\\\|x+7|\geq2\\\\Check:\\\\|x+7|\geq2\iff x+7\geq2\ \vee\ x+7\leq-2\qquad\text{subtract 7 from both sides}\\\\x+7-7\geq2-7\ \vee\ x+7-7\leq-2-7\\\\x\geq-5\ \vee\ x\leq-9\qquad CORRECT\ :)

Find the value of x and find the value of polygon JKLM​
Leokris [45]

Answer:

  1.  (B)  73

  2. r = 15

Step-by-step explanation:

1. The sum of angles in a triangle is 180°.

  62° +45° +k° = 180

  k = 180 -107

  k = 73

__

2. The sum of exterior angles of any polygon is 360°.

  4r° +7r° +5r° +8r° = 360°

  24r = 360 . . . . . . . . . . . . . collect terms, divide by °

  r = 360/24 . . . . . divide by 24

  r = 15

Trigonometric Identities
bogdanovich [222]
\bf \textit{symmetry identities}\\\\&#10;sin(-\theta )\implies -sin(\theta )\qquad \qquad cos(-\theta )\implies cos(\theta )&#10;\\\\\\also~recall\\\\ sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)&#10;\\\\\\&#10;sin^2(\theta)=1-cos^2(\theta)&#10;\\\\&#10;-------------------------------\\\\\&#10;[1-cos(-t)][1+cos(t)]\implies [1-cos(t)][1+cos(t)]

\bf 1^2-cos^2(t)\implies 1-cos^2(t)\implies sin^2(t)\\\\&#10;-------------------------------\\\\\&#10;%Simplify each expression.  (1−cos⁡(−t))(1+cos⁡(t)) =  (1+sin(t))(1+sin(-t))=  csc⁡(t)tan⁡(t)+sec⁡(−t) =&#10;[1+sin(t)][1+sin(-t)]\implies [1+sin(t)][1-sin(t)]&#10;\\\\\\&#10;1^2-sin^2(t)\implies 1-sin^2(t)\implies cos^2(t)\\\\&#10;-------------------------------\\\\

\bf csc(t)tan(t)+sec(-t)\implies \cfrac{1}{\underline{sin(t)}}\cdot \cfrac{\underline{sin(t)}}{cos(t)}+\cfrac{1}{cos(-t)}&#10;\\\\\\&#10;\cfrac{1}{cos(t)}+\cfrac{1}{cos(-t)}\implies \cfrac{1}{cos(t)}+\cfrac{1}{cos(t)}\implies \cfrac{2}{cos(t)}&#10;\\\\\\&#10;2\cdot \cfrac{1}{cos(t)}\implies 2sec(t)
