Answer:

B. The argument is invalid because the conclusion does not follow the premises.

Step-by-step explanation:

It is given △ABC and △QRS are congruent.In congruent triangles corresponding sides and angles are equal.

Thus the conclusion The corresponding angles of △ABC and △QRS are not congruent is not a valid statement.

If the triangles are congruent then the conclusion reached is not following the given statement .Hence The argument is invalid because the conclusion does not follow the premises.

Option B is the right answer.

Describe an easy way to find the square root<br> when the number is not a perfect square?

marissa [1.9K]

The product of a rational number multiplied by itself is called as a perfect square.,we can easily find out the square root for a number which is a imperfect square

Step-by-step explanation:

using the following formula we can find a square root for a number which is a imperfect square

X = Non perfect square

√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )

$√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )$ Example

√38

the nearest perfect root is 36

36 (√36=6)

so √38 = √36 + (38-36)/2√36

= 6 + 2/12

=6 + 1/6 = 6.166 (answer)

$√38 the nearest perfect root is 36 36 (√36=6)so √38 = √36 + (38-36)/2√36 = 6 + 2/12=6 + 1/6 = 6.166 (answer)$
