Answer:
150 sq.cm
Step-by-step explanation:
total surface area of a cube is
(where a = measure of each side of the cube)
so, TSA = 6 × 5 × 5 = 150 sq.cm
X=[(x+60°)-20°]/2
x=(x+60°-20°)/2
x=(x+40°)/2
Solving for x: Multiplying both sides of the equation bu 2:
2x=2(x+40°)/2
2x=x+40°
Subtracting x both sides of the equation:
2x-x=x+40°-x
x=40°
Answer: x=40°
Answer:
The answer is -4.
Step-by-step explanation:
Start with distribution: -6x+9=33
Additive Inverse of 9: -6x+9=33
-9 -9
----------------
Divide both sides by -6: -6x = 24
x=-4
