Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) = 
A = 
A = 38.21°
A ≈ 38°
Option (3) will be the correct option.
Let
x = height of BigFoot 5
y = height of Bigfoot 2
We must write an expression that relates both heights:
y = (1 / 4.9) * x
Then, replacing the height of BigFoot 5
y = (1 / 4.9) * (15.4) = 3.14cm
answer
the height of Bigfoot 2 is 3.14cm
If you annual income form a Part time job is $2,698 and the inflation rate is
Answer:
D) 8
Step-by-step explanation:
You multiply 10 by 12 to get 120 so you multiply x by 12 to get 96.
96 = 12x
/12 /12
8 = x
17÷25=0.68
So it terminates.
