Your answer to this is
V= a²
Answer:
Step-by-step explanation:
3x + 6 = 8 + 3x - 2
3x + 6 = 3x + 6
Bringing like terms on one side
3x - 3x = 6 - 6
0 = 0
Answer: They originally thought they were paying £1680

1680+12.5%1680= 1890
1680+210=1890
1890=1890
Answer:
F = 53.1°
Step-by-step explanation:
When you consider F as your angle
cos F = adjacent / hypotaneous
or, cos F = EF/DF
We do not have DF right now,
so DF² = DE² + EF²
DF = √ (12² + 9²)
DF = 15
cos F = adjacent / hypotaneous
or, cos F = EF/DF
cos F = 9 / 15
F = cos ⁻¹ (9/15)
F = 53.1°
