Answer:
The answer is 7
Step-by-step explanation:
5x7=35
it's quite hard to determine since there isn't any angle given
Answer
do 2-2-12+8-39=1
Step-by-step explanation:
The interior angles added with the corrrsponding exterior angle will equal 180 because there linear so just subtract 180 from the interior angle
180-115=65
180-40=140
180-25=155
you can check by adding up all the angle measures and seeing if it equals 360
(exterior angle of a triangle added equal 360 while interior angles added up equal 180)
Ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so
xy=15000
x+y=5
x+y=5
y=5-x
x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x=
x^2-5x+15000
a=1
b=-5
c=15000
x=
x=
x=
x=
so the numbers are
and
