Answer:
irrational number, non-repeating decimal
Step-by-step explanation:
√18 = √9·√2 = 3·√2.
√2 is an irrational, non-repeating decimal (my calculator shows it to be approx. 1.414213562..... )
and so √18 is the same.
Answer:
If EFGH is an isosceles trapezoid,
if
EH=4x-27+
FG=x%2B9+
EG=3y%2B19
FH=11y-21
then EH=FG and EG=FH
set up equations:
4x-27=x%2B9 .......solve for x
4x-x=27%2B9
3x=36
x=36%2F3
3y%2B19=11y-21.......solve for y
11%2B19=11y-3y
30=8y
y=30%2F8
y=15%2F4
y=3.75
so,x=12 and y=3.75
you can also check the length of equal sides and equal diagonals:
EH=4%2A12-27+=21
FG=12%2B9+=21
EG=3%283.75%29%2B19=30.25
FH=11%283.75%29-21=30.25x=12

Answer:
E. cot(90° -θ)
Step-by-step explanation:
The "cofunction" is named by adding or deleting the "co" in front of the function name. The cofunction for tangent is <em>cotangent</em>.
The tangent of an angle is the cotangent of the complement of the angle:
tan(θ) = cot(90° -θ)
