2x + 5y = -15 is the standard form of equation
<em><u>Solution:</u></em>
Given that,
<em><u>The point slope form of the equation of the line that passes through (-5, -1) and (10, -7) is given by:</u></em>
We have to write the standard form of the equation
The standard form of an equation is Ax + By = C
In this kind of equation, x and y are variables and A, B, and C are integers
<em><u>Let us convert the given equation into standard form</u></em>
Thus the standard form of equation is found
Answer:
Step-by-step explanation:
Let shall be considering the Cosine rule in this situation.
a^2 = b^2+c^2- 2bc.cosA
Where a = ?
b = 21km
c 45km
A = 131
a^2 = 21^2+45^2-2(21*45).cos131
a^2 = 441+2025-1890(-0.6560)
a^2 = 2466+1239.951
a^2 = 3705.951
a= 60.876km
Finding the bearing of the port from the ship.
We shall be considering the Sine rule
Sin A/a = Sin B/b
Where A = ?
a = 45km
B = 131°
b = 60.876km
Sin A/45 = sin131/60.876
SinA×60.876 = 45×sin131
SinA×60.876= 45×0.7547
SinA×60.876 = 33.961
SinA= 33.961/60.876
SinA = 0.5578
A = sin^-1 0.5578
A = 33.9°
