PLEASE HELP!!! Geometry Angles/Algebra

To get you started,

Complementary angles are angles that add up to 90 degrees.

Linear angles are angles that add up to 180 degrees.

Rewrite your equations using that information, then find a value for y or x in terms of the other variable, then substitute it in the other equation.

PLEASE HELP!!! Geometry Angles/Algebra

(9x+7y)+(3x-2y)+(7y)=180

y=15-x

There are many possibilities that make a triangle:

Graph the following:

7y>=0

7y<=180

3x-2y>=0

3x-2y<=180

9x+7y>=0

9x+7y<=180

y=15-x

You discover that any value of 'x' between 6 & 15 (not including the end points) gives a solution meeting the specified criteria.

x=14 gives m(a)=133 m(b)=40 m(c)=7

x=7 gives m(a)=119 m(b)=5 m(c)=36

x=10.5 gives m(a)=126 m(b)=22.5 m(c)=31.5

x=sqrt(63) gives m(a)=120.875 m(b)=9.686 m(c)=49.439

x=4*pi gives m(a)=130.133 m(b)=32.832 m(c)=17.035

You get the picture.

Interesting problem, but do we really have the right question? This one seems a little complex for standard usage.

Let us know.
