I don’t really know exactly to what degree you need to put in your solution. But I rounded to the nearest tenth degree.
A = 112 degrees
B= 28 degrees (180-112-40 bc all sides of a triangle must equal 180)
C= 40
a= 27.6 (this is the side opposite of angle A)
b= 14 (side opposite b)
c= 19.2 (side opposite c)
HOW TO SOLVE:
c= law of sines, so c/sin(40) = 14/sin(28), multiply both sides by sin(40) so c can be isolated and solved for. c = 14sin(40)/sin(28). Plug into calculator then get answer. c is approximately 19.2.
a = law of sines again, so a/sin(112) = 14/sin(28). Multiply both sides again by sin(112) then solve. a = 14sin(112)/sin(28). Calculator again. a is around 27.6

Answer:
312
Step-by-step explanation:
Triangles
1/2 12 *10 = 6*10 = 60
there are two triangles meaning we have to multiply 60 by 2 = 120
Rectangle
12*16 = 192
Add the two and you have the area 120+192=312
Answer:
63
Step-by-step explanation:
3×9= 27
4×9= 36
27+36= 63
Answer:
8%
Step-by-step explanation:
Given that:
Reliability of each = 0.92
r = 0.92
1 - (1 - r)(1 - r) = 1 - (0.08)(0.08) = 1 - 0.0064 = 0.9936
Percentage improvement :
1 - (0.9936) / r
1 - (0.9936 / 0.92)
1 - 1.08
= - 0.08
= 0.08 / 100 = 8%
