Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30

Answer:
I wasn't sure if you meant centimeters, inches or degrees. But since I don't know, I'll answer all three.
Step-by-step explanation:
Centimeters- Possible
Inches- Possible (Extremely big. I suggest using a big whiteboard to draw out)
Degrees- Impossible (All degrees in a triangle have to add up to 180)
