Answer: the correct answer here would be C
Step-by-step explanation: because there is everything except a gap
Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
Answer:
A= 2/B= 1/C= 4
Step-by-step explanation:
If a+b equals to 3, then the equation has to be 2+1. Then the value B has to be smaller than C to make a positive number, so B= 1 and C= 4.
