Answer:


x=85\\ \\y=100\\ \\z=100

Explanation:

Angles with measures of
95^(\circ) and
x^(\circ) are supplementary angles, thus, they add up to
180^(\circ):


x+95=180\\ \\x=180-95\\ \\x=85

Angles with measures of
80^(\circ) and
y^(\circ) are supplementary angles, thus, they add up to
180^(\circ):


y+80=180\\ \\y=180-80\\ \\y=100

Find the measures of two remaining interior angles of the pentagon:


1. \ 180^(\circ)-62^(\circ)=118^(\circ)\\ \\2.\ 180^(\circ)-53^(\circ)=127^(\circ)

The sum of the measures of all interior angles in the pentagon is


(5-2)\cdot 180^(\circ)=540^(\circ),

then


95^(\circ)+118^(\circ)+100^(\circ)+z^(\circ)+127^(\circ)=540^(\circ)\\ \\440^(\circ)+z^(\circ)=540^(\circ)\\ \\z^(\circ)=100^(\circ)
