I believe there are 210 blue counters in the bag im not sure but this is how i got this.
a whole will =1
1-.3=.7
there are 90 blue counters in .3 and there are 2.33333(repeat) in .7
so i multipled 2.3333(repeat) by 90. 2.3333(repeat)*90=210
-hope i got it right and that this helps-
p.s. i know it was confusing i have a very different way of thinking, lol.
Answer:
0.3.
should be the answer im sorry if I'm wrong
You know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)
because you are finding the angle you would go Tan^-1(12÷20) =31°
it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20
Your answer is 31°
Answer:
cosA = - 
Step-by-step explanation:
Using the double angle identity
cos2A = 2cos²A - 1 , then
cosA = 2cos²(
) - 1 , that is
cosA = 2 × (
)² - 1
= 2 × 
- 1
= 
- 
= -
A. angel a is 50 bc since it is isosceles, the two ungiven angles equal the same (180-80=100, 100/2=50)
B. 180=28+28+b, 180=56+b, 124=b
