How can you remember the difference between supplementary and complementary angles

I always remembered it as the 's' (for supplementary) is farther than 'c' (for complementary) in the alphabet just like 180 degrees is farther than 90 degrees

so supplementary is 180 degrees
complementary is 90 degrees

A plot of land has an area of 1,089,000 square feet.The conversion factors between different area measures are shown below.27,87
IgorC [24]

Part A) 24.79 acres

1) Since that plot has an area of

1,089,000ft^2=1.08\times10^6ft^2

And the number of units must be between 10 and 10² units.

Part A)

\begin{gathered} 27,878,400ft^2=2.78784\times10^7ft^2=1m^2 \\ 43560ft^2\text{ =4.356 }\times10^4ft^2\text{ = 1 acre} \end{gathered}

2) Let's convert them to the apparently plausible units, see if it fits within the given interval.

\begin{gathered} \frac{1.08\times10^6}{4.356\times10^4}=24.79\text{ acres} \\ \frac{1.08\times10^6}{2.78784\times10^7}=0.03m^{2} \end{gathered}

We can see that 0.03 m² does not belong to the given interval.

3) Hence, the answer is 24.79 acres.

PLEASE HELP!!! I need the answer and the work to go along with it.
Masja [62]
----------------------------------------------------------------------------------------------------
Check the picture attached.

the secants of the circle, BA and DC, intersect at point P, as shown.

i)
let m(P)=a

ii)
let m(CDA)=b, then the measure of ar CA is 2b, as "the measure of an inscribed angle is half the measure of the arc it intercepts"

iii)
m(DAB)= m(P)+m(CDA)= a+b, as DAB is an exterior angle of the triangle PAD.

iv)
then the measure of arc DB is 2m(DAB)=2(a+b)=2a+2b

v)
m(P)= \frac{(2a+2b)-2b}{2}= \frac{m(DB)-m(CA)}{2}

This is always true,
----------------------------------------------------------------------------------------------------

In our problem, there is a slight difference, we have 1 secant and one tangent, but it is just a special case and nothing changes.

As an exercise, we can repeat the steps of the general proof, by first joining U and T.
----------------------------------------------------------------------------------------------------

by the theorem we just proved,

m(R)=(m(TU)-m(SU))/2

30°=(100°-m(SU))/2

60°=100°-m(SU)

m(SU)=40°
