C) 90.16
sin (48°) = 67 / x
x • sin (48°) = 67
x = 67 / sin (48°)
x = 90.16
No problem!

A figure with absolutely no endpoints is called a "line".
Answer:
cost = 1296 × 2 = $2592
Step-by-step explanation:
The concrete is likely a rectangular prism base on it dimension . The width, length and height is known. The volume of the prism should be calculated since the concrete prize is known base on it volume.
volume of a rectangular prism = Lwh
where
L = length
w = width
h = height
volume = Lwh
volume = 18 × 18 × 4
volume = 1296 ft³.
The cost of the concrete is $2 per cubic ft. Therefore, the volume for 1296 ft³ can be calculated below
$2 is the cost for 1 cubic fit
how much for 1296 cubic ft
cross multiply
cost = 1296 × 2 = $2592

Since each side are congruent, you set the two sides to each other
7x-12=3x
Subtract 7x from both sides
-12=-4x
Divide -4 from both sides
3=x
3+3+3=9
18. 28
2x-3=3x-10
Add 10 on both sides
2x+7=3x
Subtract 2x on both sides
7=x
7+7+7+7=28
