AB means A X B so you have to do 14 / 9 which is 1.5 or there abouts.
So if 18 + x =43, then what you need to do is
18 + x =43
-18 -18
——————
x = 25
because whatever you do to one side, you need to do to the other
Answer:
8.212°
Step-by-step explanation:
Hypotenuse^2=base^2+perp^2
(8)^2=(7)^2+(perp)^2
64=49+(perp)^2
64/49=perp^2
1.306=perp^2
Now taking sq root on both sides
Perp=√1.306
Perp=1.142
Sin C=opposite/hypotenuse
Sin C=1.142/8
Sin C=0.14285
C=Sin^-1 0.14285
C=8.212°
