Answer:

  C. Only Henry's proof is correct.

Step-by-step explanation:

Amy's "proof" leaves out the steps that Henry's proof puts in. Only Henry's proof is correct.

__

Amy's proof has no reasoning to support her "therefore ..." and no reasoning to support her conclusion that angles 4 and 2 are equal. Nothing in her proof supports her conclusion that the transitive property of equality can be applied.

MA_775_DIABLO [31]

Answer:

7.7 is the answer

Step-by-step explanation:

(credit to manics.info)

Step 1:

Calculate the square root of 60 to be:

√60 = 7.74596669241483

Step 2:

Reduce the tail of the answer above to two numbers after the decimal point:

7.74

Step 3:

Round 7.74 so you only have one digit after the decimal point to get the answer:

7.7

To check that the answer is correct, use your calculator to confirm that 7.72 is about 60.

Hope this help and have a great day!
