Answer:
k=6
Step-by-step explanation:
18=k+12
you need to isolate k so you subtract 12 from both side
6=k
Answer:
solve the equation by rewriting in exponential form using the definition of a logarithm and simplifying.
Exact Form:
x= 1/10000
Decimal form:
x=0.0001
Given:
Measure of arcs 50°, 115° and 85°
To find:
The measure of the numbered angle 5.
Solution:
Let the missing arc measure be A.
The arc measure of a full circle is 360°
m(ar A) + 50° + 115° + 85° = 360°
m(ar A) + 250° = 360°
Subtract 250 from both sides.
m(ar A) = 110°
<em>If two chords intersects inside a circle, then the measure of the angle formed is half of the sum of intercepted arcs.</em>
![$\Rightarrow m\angle 5 =\frac{1}{2} (110^\circ+115^\circ)](https://tex.z-dn.net/?f=%24%5CRightarrow%20m%5Cangle%205%20%3D%5Cfrac%7B1%7D%7B2%7D%20%28110%5E%5Ccirc%2B115%5E%5Ccirc%29)

![$\Rightarrow m\angle 5 =112.5^\circ](https://tex.z-dn.net/?f=%24%5CRightarrow%20m%5Cangle%205%20%3D112.5%5E%5Ccirc)
The measure of the numbered angle is 112.5°.
