Answer:
1. 6.61
2. 5.89
3. 31.42
4. 38. 36
Step-by-step explanation:
A triangle is 180 degrees so H is 27 degrees
Use sine rule to find 1:
3/sinH=x/sinI
3/sin27=x/sin90
Sin90 becomes 1
3/sin27=x
x=6.61
2.
Use pythagoras theorem
c^2=b^2+a^2
You now know c and a
b^2=6.61^2-3^2
B=(squareroot of) 34.6921
B=5.89
3.
Triangle has 180 degrees. 180-90-55=35
Use sine rule
22/sin35=y/sin55
y=31.42
4:
Pythagoras theorem
c^2=a^2+b^2
c=(squareroot of) 484+987.2164
c=38.36
