PLZ HELP

Alex

Answer:

The correct option is C ) 109.5°

Therefore,

$m\angle E=109.5\°$

Step-by-step explanation:

Given:

In Triangle DEF

d = 10

e = 18

f = 12

To Find

angle E = ?

Solution:

In Triangle DEF , Cosine Rule says

$\cos E=\dfrac{f^{2}+d^{2}-e^{2}}{2fd}$

Substituting the values we get

$\cos E=\dfrac{12^{2}+10^{2}-18^{2}}{2\times 12\times 10}$

$\cos E=\dfrac{-80}{240}=-\dfrac{1}{3}$

Therefore,

$\angle E=\cos^{-1}(-0.3333)$

$m\angle E=109.5\°$ ............As it is in Second Quadrant

Therefore,

$m\angle E=109.5\°$

Please help! How do I solve this?

Advocard [28]

$m\angle 6=m\angle3\\
8x+7=6x+32\\
2x=25\\
x=12.5\\\\
m\angle 6=8\cdot12.5+7=100+7=107\Rightarrow D

Which statements are true when using algebra tiles to solve the equation 8x + (–4) = 11x + 5?

kogti [31]

Answer:

See explanation

Step-by-step explanation:

You are given the equation $8x+(-4)=11x+5$

1. Add 8 negative x-tiles to both sides of the equation to create a zero pair on the left side. The equation then will have form

$8x+(-4)+(-8x)=11x+5+(-8x)\\ \\-4=3x+5$

2. Add 5 negative unit tiles to both sides of the equation to create a zero pair on the right side. The equation now is

$-4+(-5)=3x+5+(-5)\\ \\-9=3x$

3. Divide both sides by 3:

$\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3$

Study the following data set.

Katen [24]

The interquartile range of the data set is 8

<h3>How to solve for the interquartile range</h3>

To do this we have to arrange in ascending order

= 8,9,9,9,10,11,13,15,17,18,22

Q2 = The median of the data is 11.

We have to find the median of the half before 11 and the median of the half after 11.

We would have

8,9,9,9,10

Q1 = 9

And 13,15,17,18,22

Q3 = 17

The interquartile range is

Q3 - Q1

= 17 - 9

= 8

The interquartile range of the data set is 8
