Answer: C) 4 x 3 cm
Step-by-step explanation:
The only dimension affected by the cut was 5, because the cut was perfectly parallel to the 4x3 face.
29.8 ÷ 3 is 9.9333 repeating
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.

c^2 = 125
c = √125 = √(25•5) = = 5√5</span>
