Answer:

The measure of one angle is $113.6^o$ , and the measure of the other one is $66.4^o$

Step-by-step explanation:

Recall that supplementary angles are those whose addition renders $180^o$

We need to find the measure of two such angles whose difference is precisely $47.2^o$ .

Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

$x+y=180^o\\x-y=47.2^o$

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

$x+y=180^o\\x-y=47.2^o\\\\2x=180^o+47.2^o\\2x=227.2^o\\x=113.6^o$

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":

$y=180^o-x\\y=180^o-113.6^o\\y=66.4^o$

I=Ishaan
C=Christopher
I/3=C
I-14=C
Substitute
I/3=I-14
I=3I-42
-2I=-42
Ishann = 21

Answer:

0.25 or 1/4

Step-by-step explanation:

2 x 1 1/4 = 2 x 1.25 = 2.5 or 2 1/2

2.5 divided by 10 = 1/4 or 0.25
