Answer:
127
Step-by-step explanation:
15+38+a=180
a= 127
Answer:
One
Step-by-step explanation:
Find the value of B
Applying the law of sines
= 
substitute the given values
= 
sin (B) =
Sin(61)
step 2
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
61 + 65.87 + C = 180
C = 53.13
step 3
Find the value of c
Applying the law of sines
= 
substitute the given values
= 
c =
SIN (53.13)
C=21.04 units
so
there can only be one value for each measurement, therefore there can only be one triangle
This is the concept of trigonometry, to solve the question we proceed as follows;
sec(x)=1/cosx
thus;
sec(205)=1/cos205
=1/-0.9063
=-1.1034
this implies that:
sec(205)<-1
