Answer:
10√3 feet
Step-by-step explanation:
In a 30-60-90 triangle;
-Long leg = long leg
-Short leg = 1/2 * long leg
-2nd longest leg = short leg * √3
-Long leg = 20
-Short leg = 1/2 * long leg = 10
-2nd longest leg = short leg * √3 = 10√3
Answer: 17.3ft
Step-by-step explanation:
Using sine rule
((sin base)/20)= ((sin suzy)/y)
suzy= 180-(90+30)= 180-120=60
((sin 90)/20)= ((sin 60)/y)
(1/20)= (0.8660/y)
Cross multiply
y= 0.8660*20
y= 17.3
