Is the sentence true or false?
Law of sine can also be written as sin(A)a=sin(B)b=sin(C)c\frac{\sin\left(A\right)}{a}=\frac{\sin\left(B\right)}{b}=\frac{\sin\left(C\right)}{c}asin(A)=bsin(B)=csin(C)
True
False
Fill in the blank:

1
None
In triangle ABC angle B = 40 degrees, angle C= 60 degrees and side a=7 units. What is the length of side c using the Law of Sines?"
5.5
9.4
6.15
7.9
To use the Law of Sines to solve oblique triangle (ASA), two angles and ______ of the triangle should be known.
a) two adjacent sides
a non-included side
side between the given angles
none
In oblique triangle if angles A, B and side c is given then the length of side c is given by:
a=bsinsin(B)a=\frac{b}{\sin\sin\left(B\right)}a=sinsin(B)b
a=c(sin(A))sin(C)a=\frac{c\left(\sin\left(A\right)\right)}{\sin\left(C\right)}a=sin(C)c(sin(A))
a=b(sinsin(C))sin(B)a=\frac{b\left(\sin\sin\left(C\right)\right)}{\sin\left(B\right)}a=sin(B)b(sinsin(C))
a=bsin(B)sin(A)a=\frac{b\sin\left(B\right)}{\sin\left(A\right)}a=sin(A)bsin(B)
In ASA-oblique triangle the ratio of the length of a side to the sine of the angle opposite that side is a constant value.
Law of sine to solve ASA triangle a/c =
(a/c)= sinsin(A)×sinsin(C)
(a/c)= sinsin(A)/sinsin(C)
(a/c)= sinsin(A) +or - sinsin(C)
(a/c)= sinsin(A)sinsin(C)
In Law of Sines to solve oblique triangle (ASA), the sum of two given angle should be ______.
Equal to third angle
Right angle
Squair of third angle
In oblique triangle when two angles and a side between these angles is known, then______ law is used.
Law of sine
Law of cosine
Lae of tangent
Identity law
In Law of Sines to solve oblique triangle (ASA), reaming two sides are always equal
It is done.
