Answer:
x= 29°
y= 73°
z= 102°
Explanation:
x is on the opposite side of the 29° which means it is equal to 29°
In order to find y we can add 29°+78° and subtract it from 180° since all triangles add up to 180°.
This makes y = 73°
In order to find z, we can subtract 78 from 180 since all straight lines are 180 degrees.
This makes z = 102°
