78- acute
144- obtuse
This is because anything less than 90 degrees is acute. Think of it as they are cute because they are tiny xD
=90 is right angel
And anything above 90 and below 360 is obtuse because it's fat xD
Answer:
Ann=£38
Bill=£171
Chloe=£95
Dave=£95
Step-by-step explanation:
By the information provided we can create an equation:
Now that we know x, we multiply it correspondingly.
For Ann -> 2*19=38
Bill -> 9*19= 171
Chloe and Dave have the exact same amount each (because they both have 2.5 times the amount Ann's money)
Chloe/ Dave -> 5*19=95 each.
Hello,
do you know what 6% equals in decimal?
With such information, all you must do is multiply the decimal value of 6% to 8000, then add that value to 8000 for the markup value.
Answer:
∠ a = 60° , ∠ b = 120°
Step-by-step explanation:
Supplementary angles sum to 180° then
x - 40 + x + 20 = 180 , that is
2x - 20 = 180 ( add 20 to both sides )
2x = 200 ( divide both sides by 2 )
x = 100
Then
∠ a = x - 40 = 100 - 40 = 60°
∠ b = x + 20 = 100 + 20 = 120°
