Add 31 to both sides which will give you
9h = 130
Answer:
N= -44/9 Hope this helped, <3
Step-by-step explanation:
Let's solve your equation step-by-step.
n−2=10n+42
Step 1: Subtract 10n from both sides.
n−2−10n=10n+42−10n
−9n−2=42
Step 2: Add 2 to both sides.
−9n−2+2=42+2
−9n=44
Step 3: Divide both sides by -9.
Using the Law of Sines, sina/A=sinb/B=sinc/C (although there are other ways considering that this is a 30, 60, 90 degree triangle with a basic identity) we can say:
97/sin60=x/sin30=y/sin90
x=97sin30/sin60 and y=97sin90/sin60
The total height of the tree is h=x+y so
h=97sin30/sin60 + 97sin90/sin60
h≈168.01 ft (to the nearest hundredth of a foot)
h≈168 ft (to nearest foot)
Answer:
The correct expression is n + 8
The value of the expression = 5.3 + 8
The answer is 13.3
Step-by-step explanation:
The expression for eight increased by a number
Assume that the number is n
Increased eight by n means add n to eight
The correct expression is n + 8
When n = 5.3
Substitute 5.3 for the variable n
The value of the expression = 5.3 + 8
Simplify by adding 5.3 and 8
5.3 + 8 = 13.3
The answer is 13.3
I think it is angle number 9
