Answer:
b=5.3 units
Step-by-step explanation:
area = 24 sq. ft
24 = 1/2 (bh)
h = 9
1/2(9)=4.5
24=4.5b
24/4.5 = 5.3
Use the cosine ratio, as you have the adjacent and hypoteneuse.
So, set up cos50=2/x, but with the variable on the bottom,the cos50 and x switch places
x=2/cos50
x=3.11
Answer:
5x+2y=4
Step-by-step explanation:
Answer:
C. 10
Step-by-step explanation:
You can take the blank as x
so 361.2 / x = 36.12
multiply by x
361.2 = 36.12x
divide
x = 10
Step-by-step explanation:
subtract the whole equation by 85 on both sides to get v by itself on the left side
85-85-v=213-85
-v=128
Now we divide the whole equation by negative 1
-1v/-1=128/-1
v=-128
Hope that helps :)
