Equ 1: X-Y=5
equ 2: x∗y=36
from Equ 1
X=5+Y------equ 3
substitute x=5+y in equ 2
(5+y)∗y=36
5y+y^2=36
y^2+5y-36=0
factorize by substitution
(y^2+9y)-(4y-36)=0
y(y+9)-4(y+9)=0
(y-4)(y+9)=0
y=4 or y=-9....
substitute y=4 or -9 in equ 1
x-4=5
x=5+4
x=9 OR
x-(-9)=5
x+9=5
x=5-9
x=-4
since -4∗-9=36
therefore y=-9 and x=-4
Answer is z=36
First find the ratio of the similar sides
55/44 = 1.25 ratio
Divide 45 by the ratio to find z
45/1.25 = 36
A counterexample is seen in the third term, 3, which does not equal 1*2=2.
1*2=2 NOT 3
Hello,
ρ=√(4²+3²)=5
tan θ=-3/-4=3/7
==>θ=216,869897...° (since θ is in the III quadrant)≈216.9°
Answer C
Given that these are all regular, 4 is 173.7. 5 is 98.7. 6 is 90.8.
