Answer:
<em>x = 59</em>
Step-by-step explanation:
<u>Equations</u>
The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
The image shows a four-sided polygon and its four angles measures, thus we sum them all and equate the sum to 360:
x + x + 2x + 3 + 2x + 3 = 360
Simplifying:
6x + 6 = 360
Subtracting 6:
6x = 354
Dividing by 6:
x = 354/6
x = 59
A plot of residuals (vertical deviations from the regression line) shows the errors or lack of fit, so it would indicate a good fit if the residuals are small, vs. over fit if they are large. Due to age related growth short pre teen, and a plateau after age 21, I would expect a linear regression would offer estimate age 5.5 years.
Answer:
15.01
Step-by-step explanation:
From the diagram above, the following were obtained:
Adj = 7
0 = 65°
Opp =?
Tan0 = Opp /Adj
Tan65° = Opp/ 7
Cross multiply
Opp =7 x Tan65°
Opp = 15.01

Answer:
The actual height of the observation deck is 1206.82 ft
Step-by-step explanation:
Let h be the height of the building
And d be the height of the observation deck
Therefore,
d/h = 8.3/10 = 0.83
d = 0.83h
Given that h = 1454 ft
d = 0.83 × 1454 ft
d = 1206.82 ft
