Answer:

Part 1)
x=35^o

Part 2)
y=30^o

Explanation:

Part 1) Find the value of x

we know that

The diagonal of the figure divide the kite into two congruent triangles

so


(3x+5)^o=(4x-30)^o

solve for x

Group terms


4x-3x=5+30


x=35^o

Part 2) Find the value of y

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so


y^o+(3x+5)^o+(2y-20)^o=180^o

substitute the value of x


y^o+(3(35)+5)^o+(2y-20)^o=180^o


y^o+(110)^o+(2y-20)^o=180^o

solve for y

combine like terms


(3y+90)^o=180^o


3y=90^o


y=30^o
