A straight angle measures 180 degrees.
Angle x and the 150-degree angle form a straight angle.
x + 150 = 180
x = 30
Angle z and the 100-degree angle form a straight angle.
z + 100 = 180
z = 80
Now you know the measures of two angles of the three angles of the triangle. The sum of the measures of the angle of a triangle equals 180 degrees.
x + y + z = 180
30 + y + 80 = 180
y + 110 = 180
y = 70
Answer: x = 30; y = 70; z = 80

9*2/9= 18/9= 2kg
5*7/25= 35/25= 1 10/25= 1 2/5 kg
1 2/5kg+2kg= 3 2/5kg or 3.4kg
total mass equals 3 and 2/5kg or 3.4kg
