Answer:
Step-by-step explanation:
29 5x+8+x+4=90
6x=78
x=13
30 3x-7+11x-1=90
14x=98
x=7
31 3x+x+8=180
4x=172
x=43
32 6x-1+5x-17=180
11x=198
x=18
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:
Second answer
Step-by-step explanation:
first answer: 4 negative numbers multiplied = 2 postive numbers multipled = 1 positive number
second answer: 3 negative numbers multiplied = 1 positive number multiplied by 1 negative number = 1 negative number
third answer: Negative and positive numbers multiplied by zero = 0
fourth answer: 2 negative numbers multiplied by 2 positive numbers = 1 positive number multiplied by 1 positive number = positive number.
3.69/10 = .369 x 12 = 4.428, so around 4.43
