<h3>
Answer: approximately 6.3 miles</h3>
=================================================
Explanation:
See the diagram below. The two given angles B = 105 and C = 20 are used to help find angle A
A+B+C = 180
A+105+20 = 180
A+125 = 180
A = 180-125
A = 55
Then we use the law of sines to find the side length c
sin(A)/a = sin(C)/c
sin(55)/15 = sin(20)/c
c*sin(55) = 15*sin(20) ... cross multiply
c = 15*sin(20)/sin(55) .... divided both sides by sin(55)
c = 6.26294249724791 .... value is approximate
c = 6.3 ....... rounding to one decimal place
Both of these are ways to express linear equations.
is the equation for a line with slope <em>m</em> which contains the point 
. This is called point-slope form.
is the equation for a line with slope <em>m</em> and y-intercept b. That is, it contains the point (0, b). This is called slope-intercept form.
Both of these are perfectly valid ways of writing lines, though sometimes one will be easier to use than the other.
Answer: D. 100
Step-by-step explanation:
Answer:
five times x plus y equals two times y plus twelve
Step-by-step explanation:
With each additional pathway, there is LESS resistance. When the filament of a bulb breaks in a series circuit, it opens the circuit and the 2nd light bulb does not light. When the same thing happens in a parallel circuit, the electrons still flow through the remaining closed circuit and light the bulb.
