it is 56
because you need to break the figure into two parts
5 x 4 = 20
4 x 9 = 36
1. It's a sine relationship => sinA = 25 / 34 => A = 47.
2.It's a cosine relationship => cosA = 26 / 35 => A = 42.
Hi! i believe the answer is a, because if b (in this case 0.2) is less than 1 and greater than 0 its exponential decay!! good luck with the rest of your hw and i hope this helps
Answer:
A+B+C=180°( BY SUM OF ALL ANGLE IS 180°)
70°+40°+C=180°
110°+C=180°
C=180°-110°
C=70°
C+X=180°(BY LINEAR PAIR)
70°+X=180°
X=180°-110°
X=70°
