Angle measures for 10 points

x = 76°

y = 128°

z = 16°

Step-by-step explanation:

JKLM is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

x + 104° = 180°

x = 180° - 104°

y + 52° = 180°

y = 180° - 52°

By inscribed angle theorem:

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
