Answer:
1.81 kilograms
Step-by-step explanation:
1.Simplify.
-2{x}^{2}-4x+13+12{x}^{2}+2x-25−2x2−4x+13+12x2+2x−25
2.Collect like terms.
(-2{x}^{2}+12{x}^{2})+(-4x+2x)+(13-25)(−2x2+12x2)+(−4x+2x)+(13−25)
3.Simplify.
10{x}^{2}-2x-1210x2−2x−12
a triangle needs to have 180 degrees in all.
65 + 65 = 130
180 - 130 = 50
x = 50 degrees
