The horizontal distance between zack and the water fountain will be 141.05 feet.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
Zack is standing at the top of a lookout tower and spots a water fountain below. If the lookout tower is 75 feet tall and the angle of depression is 28°.
Then the horizontal distance between zack and the water fountain is given as,
tan 28° = 75 / x
x = 75 / tan 28°
x = 75 / 0.5317
x = 141.05 feet
The horizontal distance between zack and the water fountain will be 141.05 feet.

Find the exact value of Cosine (alpha + beta) given sin Alpha = two-fifths for Alpha in Quadrant II and Cosine Beta = one-third for Beta in Quadrant IV.
The exact value of cos (α + β) is (4√2-21) / 15.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
Sin α = 2/5, and α is in second quadrant,
cos β = 1/3 , and β is in fourth quadrant
Since, α is in second quadrant, the value of cos α will be negative.
The value of cos α, by right angle triangle property,
cos α = -√21 / 5
Since, β is in the fourth quadrant, the value of sin β will be negative.
The value of sin β = - 2√2 / 3
Cos (α + β) = cos α.cos β - sin α. sin β
Substitute the values here,
Cos (α + β) = (-√21 / 5) . 1/3 - 2/5. ( - 2√2 / 3)
= -21/15 + 4√2/15
= (4√2-21) / 15
The value of cos (α + β) is (4√2-21) / 15.

Write the equation of a line that is
parallel to y = 0.5x + 6 and
passes through the point (6, -2).
Answer:
[tex]y=0.5x-5[/tex]
Step-by-step explanation:
Since the equation is parallel, this means that the slope remains the same which is 0.5.
The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.
[tex]-2=0.5(6)+b[/tex]
When solving for b, it will equal to -5.
Therefore the new equation that is parallel is [tex]y=0.5x-5[/tex]
The equation of a line parallel to y = 0.5x + 6 and passes through the point (6, -2) is y = 0.5x + 1.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know lines parallel to each other have the same slope.
The given line can be written as y = 0.5x + 6.
Therefore, The required line also has a slope of 0.5 passing through the point (6, -2).
- 2 = 0.5×6 + b.
- 2 = - 3 + b.
b = 1.
So, y = 0.5x + 1.
