Answer:
using pythagoras theorem
a^2+b^2=c^2
8^2+x^2=(x+2)^2
64+x^2=x^2+2*x*2+2^2
64+x^2=x^2+4x+4(here x^2 of left hand side and x^2 of right hand side gets cancel)
64=4x+4
64-4=4x
60/4=x
15=x
Step-by-step explanation:
Angle AOB + angle BOC = angle AOC
7x + 30 + 9x + 42 = 104
16x = 104 - 72
16x = 32
x = 2 degrees
Angle BOC = 9x + 42 = 18 + 42 = 60 degrees
The domain of it is d: [1,+infinity) and the range is r: (-infinity,0].
Answer:
i dont know you
Step-by-step explanation:
who are you
To find the number of feet she jumped you have to divide 156 by 12 because there are 12 inches in a foot
So 156/12 =13
So she jumped 13 feet
