Fill in the blank:
The Law of sine is also known as_______.
Sine formula
sine rule
both (a) and (b)
Is the sentence true or false?
In oblique triangle if angles B, C and side c is given then the length of side a is given by:
a=c(sinsin(B))sin(C)a=\frac{c\left(\sin\sin\left(B\right)\right)}{\sin\left(C\right)}a=sin(C)c(sinsin(B))
True
False
In oblique triangle if angles A,B and side b is given then the length of side a is given by:
a=bsinsin(B)a=\frac{b}{\sin\sin\left(B\right)}a=sinsin(B)b
a=b(sinsin(A))ca=\frac{b\left(\sin\sin\left(A\right)\right)}{c}a=cb(sinsin(A))
a=bsinsin(A)sin(B)a=b\frac{\sin\sin\left(A\right)}{\sin\left(B\right)}a=bsin(B)sinsin(A)
a=bsin(B)sin(A)a=\frac{b\sin\left(B\right)}{\sin\left(A\right)}a=sin(A)bsin(B)
In Law of sine an equation relates lengths of the sides of triangle to the ______ of triangle.
Secant of its side
sines of its sides
sines of its angles
secant of its angle
In oblique triangle if angles A,C and side a is given then the length of side b is given by
b=asin(B)sin(A)b=\frac{a\sin\left(B\right)}{\sin\left(A\right)}b=sin(A)asin(B)
The Law of sine is applicable to all types of triangles including both oblique and right-handed triangles.
Ifsin46.5x=sin39.357\frac{\sin46.5}{x}=\frac{\sin39.35}{7}xsin46.5=7sin39.35 then find the value of x.
