Answer:
x = 81, y = 68, z = 99
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left, then
x = 180 - (36 + 63) = 180 - 99 = 81
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle on the right, thus
13 + y = x , that is
13 + y = 81 ( subtract 13 from both sides )
y = 68
Consider the triangle on the right
z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99
Step-by-step explanation:
C4H6O3 + H2O => 2C2H4O2
C2H4 + 3O2 => 2CO2 + 2H2O
C4H10O + 6O2 => 4CO2 + 5H2O
Ok I think it’s 26 if I’m wrong sorry
