Answer:
w = 3
x = 25
y = 36°
z = 54°
Step-by-step explanation:
a regular rhombus has equal sides, the perimeter is 100, 100: 4 = 25 (side/x).
the diagonals are equal therefore w = 3
now we find y
the sum of the internal angles is 360 °
360 - 36 * 4 = 144
144 : 4 = 36 (y)
now we find z
the sum of the interior angles of a triangle (1/4 rhombus) is 180°
180 - 90 - 36 = 54 (z)
