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

Answer:
<em>10 feet</em>
Step-by-step explanation:
here's the reason ; -
let's take the missing side be x
we know, the one side of a triangle should always be greater than the difference between the other two sides, so ,
=》x > 7-4
=》x > 3
and the measure of a side should always be less than the some of the other two sides, hence
=》7 + 4 > x
=》11 > x
now, we have : -
11 > x > 3
value of x should be more than 3 and less than 11 , hence 2 ft , 3 ft and 12 ft can't be the measure of third side,
so, we got our third side as 10 ft
Answer:
246 ft^2
Step-by-step explanation:
First, break it into smaller rectangles:
3*6=12
6*9=54
15*12=180
Add the areas together
12+54+180=246
The area of the figure is 246 ft^2
Step-by-step explanation:
you have to multiply 20 by 80
