Can you help me with this mathswatch question please and thank you!!

a) 3.14159

b) C = 355/113

Step-by-step explanation:

a) 3.1415926536

number 2 rounds down so it stays at 9

b) π = 3.14159

A - 22/7 = 3.14286

B - 135/43 = 3.13953

C - 355/113 = 3.14159

D - (62/35)² = (1.77142857)² = 3.13796

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
