Answer:4.1
Step-by-step explanation:
c=AB
C=26°
B=122°
b=8
Using sine rule
c/sinC = b/sinB
c/sin26=8/sin122
Sin26=0.4384
Sin122=0.8480
c/0.4384=8/0.8480
Cross multiply
c x 0.8480=8 x 0.4384
c x 0.8480=3.5072
Divide both sides by 0.8480
(c x 0.8480)/0.8480=3.5072/0.8480
c=4.1
Well this is a little tricky.. But my guess would be: <span>y = (-1.4, 2.5)</span>
1) <ABC
2) 120
3) 22
4) <GFH
5) 29
6) 90
7) 45
8) 63
9) 45
10) 110
