Step-by-step explanation:
the given data is
tanθ = 2.773 and 0<θ<π/2
this implies θ = tan inverse(2.773)
⇒ θ = 70.16°
Therefore, sinθ = sin70.16° = 0.9406
similarly,cosθ = cos70.16° = 0.3393
therefore, values of sinθ and cosθ are 0.9406 and 0.3393 respectively.
The pet store had 31 frogs at the beginning of the week.
3a + 3b
combine like terms: a+a+a=3a
b+b+b=3b
3a +3b
When dividing fractions, theres this thing you do call "keep, change, flip"
You keep the first fraction the same, change the division to a multiplication, and change the fraction to have the numbers flipped.
4 = 4/1
1 1/8 = 9/8
4/1 * 8/9 = 32/9
32/9 = 3 5/9
3 5/9 is the final answer
