It opens down.
Since the beginning number -5x^2 is negative, it will open down.
Answer:
x = 12
Step-by-step explanation:
6x - 4 and 112 are same- side interior angles and sum to 180° , that is
6x - 4 + 112 = 180
6x + 108 = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
It looks like the 45
What I did was add the 60+30=90 then subtract from 180 and divided my 2 and got 45 hopes this helps!
