Angle TRS is equal to 180 - 9x (straight angles).
The sum of all the interior angles of a triangle is 180. Thus,
180 - 9x + 5x + 9 + x = 180, resulting in -9x + 5x + 9 + x = 0.
Then -4x + x = -9, or -3x = -9, or x = 3 (answer)

Answer:

Step-by-step explanation:
7x-26<-5(2-3x)
first write out the equation
7x-26<-10 +15x
then solve the -5(2-3x)
by multiplying -5 by 2 and -5 by 3x which will give the answer -10 and 15x
7x-15x<-10+26
Now put the numbers with X first and since we moved the (+15x) into the otherside we change its sign to (-15x)
and because we put the (-26) into the otherside we do the same thing and change it into (+26)
-8x<16
Now we combine the same numbers so 7x-15x and -10+26
Next we divide both sides by (-8)
so (-8x÷-8) and (16÷-8)
and because we divided with a negative number (-8)
and we have an inequality( < ) we flip the sign from smaller than to greater than.
and so the final answer is x>2
or x is greater than 2

so... what does that give you for the discriminant?
if it's a negative value, no solutions
if it's a positive value, two solutions
if it's 0, one solution
