In ΔCDE, \overline{CE}

abruzzese [7]

Answer:

$m\angle CDE=14^o$

Step-by-step explanation:

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

see the attached figure to better understand the problem

∠DEF=∠ECD+∠CDE

substitute the given values

$(4x+5)^o=(x+9)^o+(x+8)^o$

solve for x

Combine like terms

$(4x+5)^o=(2x+17)^o$

Group terms

$4x-2x=17-5$

$2x=12$

$x=6$

Find the measure of angle CDE

$m\angle CDE=(x+8)^o$

substitute the value of x

$m\angle CDE=(6+8)=14^o$

Solve the equation for the indicated variable. Please help ASAP!!!!! :(<br> A=(730x)/(d^2) for x

zvonat [6]

First let's get rid of the $d^2$ in the denominator of the fraction on the right side of the equation. This will help to get only $x$ and a coefficient on one side of the equation:

$A = \dfrac{730x}{d^2}$

$d^2A = 730x$

Now, simply divide by 730 to find $x$ :

$d^2A = 730x$

$\boxed{\dfrac{d^2A}{730} = x}$
