Answer:
8
Step-by-step explanation:
6.35- 3.15 is 3.20.
3.20÷.40=8
hope this helps :)
2.25
add 7 to both sides= 9
divide by 4 =2.25
<span>29 birds were sitting in a tree some more fly up to the tree then there were 42 birds in the tree how many more flew up to the tree</span>
13 birds 29+13=42
Sin θ = 2 / 7
tan θ > 0
cos θ = ?
sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse
short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?
adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5
cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7
