1 answer:

4 0

Sum of interior angles of polygon
(n-2) × 180 = (5 - 2) x 180 = 3 x 180 = 540
so
2x + 142 + 2x + 3x + 14 + 3x + 14 = 540
10x + 170 = 540
10x = 370
x = 37

m<M = 3x + 14
m<M = 3(37) + 14
m<M = 111 + 14
m<M = 125

Ghella [55]

Hey!!!
Answer is....
diagonals of square bisect each other at right angles.
let diagonal be 2x
Using Pythagoras in a triangle enclosed by a side and 2 half diagonals...
${x}^{2} + {x}^{2} = {10}^{2}$
$2 {x}^{2} = 100$
${x }^{2} = 50$
$x = \sqrt{50}$
side of a diagonal=2 sqrt50
$= 10 \sqrt{2}$
cm......
