Answer:
   sin(D) = cos(E) = (√3)/2
   cos(D) = sin(E) = 1/2
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between trig functions and right triangle sides.
   Sin = Opposite/Hypotenuse
   Cos = Adjacent/Hypotenuse
For this diagram, this means ...
   sin(D) = cos(E) = (13√3)/26 = (√3)/2
   cos(D) = sin(E) = 13/26 = 1/2
 
        
             
        
        
        
Answer:
a. 7.2
b. 6
Step-by-step explanation:
Since the side lengths of similar polygons are proportional to each other, therefore:

Thus, let's find b using:

Cross multiply


Divide both sides by 15
b = 6
Let's find a using:

Cross multiply
9*12 = 15*a
108 = 15a
Divide both sides by 15
a = 7.2
