Answer:
let angle e be x
x+4x+10=180°[by linear pair]
5x+10=180°
5x=180-10
5x=170
x=170/5
x=34
angle E=34°
angle E+angle C+angle D=180°[by angle sum property]
34°+70°+2x=180°
104°+2x=180°
2x=180°-104
2x=76°
angle d=76°
1:4 tennis to soccer---- 1 =5 so 4 = 5x4=20 students on the soccer team
1:2 Soccer to football ----- 1=20 so 2= 20x2= 40 students on the football team.
there are 40!
let me know if you get it right
Answer:
Step-by-step explanation:
Problems like this require that you recognize that the denominator of the right term is a factor of the denominator of the left term. That is, you're supposed to know how to recognize and factor the difference of two squares.
Answer:
B. The contradiction of the statement is proven false, so the original
statement is therefore proven true.
Step-by-step explanation:
We assume the opposite and then get to a point where we get a false statement. That proves that the the opposite of the opposite ( what we originally wanted to prove) is true.
Answer:
B
Step-by-step explanation:
rotate 180 --> translate up by 4: (x,y)--> (-x,-y) --> (-x,-y +4)
