Answer:
x=3
Step-by-step explanation:
AB+BC>AC
2x + 3 + x + 1 > x + 10
we correct like terms
2x + x + 3 + 1> x+ 10
3x + 4> x + 10
3x - x > 10-4
2x > 6
divide both sides by 2
2x÷2 > 6÷2
x = 3

1/6 page = 1 hour
1page= 6 hours
5 pages would be 30 hours
SinA= 16/20= 4/5=0.8 degree
cosA=12/20=3/5=0.6 degree
tanA=16/12= 4/3=1.33 degree
