Answer:
I'm sorry, I can help only with this one x = 20°
Step-by-step explanation:
2x + 5° + 4x + 15° + 2x = 180°
8x = 180° - 5° - 15°
8x = 160°|÷8
x = 20°
The height of Zinger 1 after 6 seconds is given by the polynomial

, for t = 6,
so the height is

(feet)
The height of Zinger 2 after 6 seconds is given by the polynomial

, for t = 6,
so the height is

(feet)
At the moment the rockets explode, Zinger 2 is 414-324=90 (feet)
higher than Zinger 1.
Answer: 90 feet
Answer:
Yup the answer is 15!
Step-by-step explanation:
(3x + 4)^(1/2) = 7

Step-by-step explanation:
tangent = opposite / hypothenus
tan C = ED / DC
tan C = 28 / 53
Answer:
D) 5√x / 4
Step-by-step explanation:
√50x^3 / √32x^2
= (5x√2x) / (4x√2)
= 5/4 √(2x/2)
= 5/4 (√x)
= 5√x / 4
