Answer:
The length of a side can be 3·√42 ft long
Step-by-step explanation:
The question is a word problem regarding the formula for the area of a square
The parameters given are;
Available concrete = Enough to pave 378 ft.²
Shape of patio Vince wants to make = Square
Therefore, the dimensions of the sides, s, of a square patio that has an area of 378 ft.² is found as follows;
s² = 378
Therefore, s = √378 = √(9 × 42) = 3·√42 ft
Hence, the length of a side can be 3·√42 ft long.

Answer:
The missing angle is 24 degrees
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
x+156 = 180
Subtract 156 from each side
x+156-156 = 180- 156
x = 24
The missing angle is 24 degrees
Answer:
1. 30
2. -10
3. 48
Step-by-step explanation:
So for #1 I did:
3*2(6)+3*8(24) which equals 30
For #2 I did:
-5*4(-20)- -5*2(-10) which equals -10
For #3 I did:
8*10(80)-8*4(32) which equals 48
