Answer:
= 112 degrees
Step-by-step explanation:
All interior angles in a triangle add up to 180 degrees
C = 180 - (a + b)
= 180 - (34 + 34)
= 180 - 68
= 112 degrees
Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
