Answer:
60
Step-by-step explanation:
You first have to do the parenthesis
(5-7)= 5-7= -2
Then just multiply -30 by -2
Since negative x negative = positive, the answer will be positive.
(-2)(-30)= -2 x -30= 60

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
