Answers

The correct answer is 45. The rule to the numbers is x + 9 and then x + 2.

12 + 9 = 21
21 + 2 = 23
23 + 9 = 32
32 + 2 = 34
34 + 9 = 43
43 + 2 = 45

Find the values of cosΘ and tanΘ, given that sinΘ = 8/9 and Θ is in quadrant I

Answers

$sin^2 \alpha +cos^2 \alpha =1\ \ \ and\ \ \ tan \alpha = \frac{\big{sin \alpha }}{\big{cos \alpha }} \n\nsin \alpha = (8)/(9)\n\n \Rightarrow\ \ \ ((8)/(9))^2+cos^2 \alpha =1\ \ \ \Rightarrow\ \ \ cos^2 \alpha =1- (64)/(81) \ \ \ \Rightarrow\ \ \ cos^2 \alpha = (17)/(81) \n\n \alpha \ \in\ (0^0;90^0)\ \ \ \Rightarrow\ \ \ cos \alpha >0\ \ \ \Rightarrow\ \ \ cos \alpha = ( √(17) )/(9) \n\n$

$tan \alpha = (8)/(9): ( √(17) )/(9) =(8)/(9)\cdot (9)/(√(17))= (8)/(√(17))= (8\cdot √(17))/(√(17)\cdot √(17))=(8\cdot √(17))/(17)$

A triangle with base on an extended line. Two angle measures are given. Top interior angle is twenty-eight degrees. Lower left exterior angle is seventy-one degrees. Lower right interior angle is labeled x degrees.

Answers

The correct answer for the question that is being presented above is this one: "The lower right interior angle is 43°"

Interior angle of a triangle and its corresponding exterior angle must have a sum of 180° when its line is extended.

Top interior angle is 28°
Lower left exterior angle is 71°
Lower right interior angle is x°

Get the left interior angle.
Exterior angle + Interior angle = 180°
71° + Interior angle = 180°
Interior Angle = 180° - 71°
Interior Angle = 109°

Top Interior angle + Left Interior Angle + Right Interior angle = 180°
28° + 109° + x° = 180°
x = 180° - 28° - 109°
x = 180° - 137°
x = 43°

The lower right interior angle is 43°

If x is a number that is 7 more than y, how do you express x as a function of y?A. x = f(y) = 7 + x
B. x = f(y) = 7 + y
C. y = f(x) = 7x
D. y = f(x) = y – 7
E. y = f(x) = 7 + y

Answers

I believe the correct answer from the choices listed above is option B. The variable y is the independent variable here and x is the dependent variable so the function can be represented as f(y). The function should be written as:

x = f(y) = 7 + y
