What is the measure of angle CXE?

miskamm [114]

Given:

m∠CXD = 30°

m∠DXE = 30°

To find:

The measure of angle CXE.

Solution:

The measure of angle CXE is sum of the measures of angle CXD and DXE.

⇒ m∠CXE = m∠CXD + m∠DXE

⇒ m∠CXE = 30° + 30°

⇒ m∠CXE = 60°

The measure of angle CXE is 60°.

Expand: In 2a^3/b^4

Ket [755]

Answer:

ln(2) +3ln(a) -4ln(b)

Step-by-step explanation:

$\ln{\left(\dfrac{2a^3}{b^4}\right)}=\ln{(2a^3b^{-4})}=\ln{(2)}+\ln{(a^3)}+\ln{(b^{-4})}\\\\=\boxed{\ln{(2)}+3\ln{(a)}-4\ln{(b)}}$

The applicable rules of logarithms are ...

log(ab) = log(a)+log(b)

log(a^b) = b·log(a)

Find the measure of each interior angle

diamong [38]

$\bf \textit{sum of all interior angles of a polygon}\\\\
180(n-2)\quad 
\begin{cases}
n=\textit{number of sides}\\
---------\\
n=10
\end{cases}\implies 180(10-2)\implies 1440\\\\
-------------------------------\\\\
\begin{array}{lclll}
&x + 5\\&x + 10\\&x + 20\\&x + 30\\&x + 35\\&x + 40\\&x + 60\\&x + 70\\&x + 80\\+&x + 90\\
&----\\
&10x+440
\end{array}\implies 
\begin{array}{llll}
10x+440=1440
\\\\\\
10x=1000
\\\\\\
x=\cfrac{1000}{10}\implies x=100
\end{array}$

so.. to get every angle, simply plug in 10 for "x" for each.

In ΔCDE, the measure of ∠E=90°, ED = 28, CE = 45, and DC = 53. What ratio represents the tangent of ∠C?

Anon25 [30]

Step-by-step explanation:

tangent = opposite / hypothenus

tan C = ED / DC

tan C = 28 / 53
