Answer:
4b = 7
Step-by-step explanation:
5x = 20 has solution x = 4
8w = 32 has solution w = 4
12y = 48 has solution y = 4
whereas 4b = 7 has solution b = 
The other 3 equations have a solution of 4 making 4b = 7 the odd one out

Answer:
Area=45
Step-by-step explanation:
Area=AC*BD/2=V12^2+(-9)^2*V6^2+8^2=(V144+81)*V36+64/2=V225*6/2=15*6/2=45
Answer:
sin A = opp / hyp = 0.82
Step-by-step explanation:
The sine function is defined as the ratio of "opposite side" to "hypotenuse."
In the given triangle, sin A = opp / hyp = 10.3 / 12.6 = 0.82 (to the nearest hundredth). That's all you have to do here.
The cosine function is the ratio of "adjacent side" to "hyp." In the given triangle, the side adjacent to angle A has length 7 .2. Thus,
cos A = adj / hyp = 7.2 / 12.6 = 0.57 (to the nearest hundredth).
