x = 4
Step-by-step explanation:
Answer:
63°
Step-by-step explanation:
From the diagram, the angle of elevation from the child to the top of the tree can be calculated using the tangent ratio.
Recall SOH-CAH-TOA from your Trigonometry class.
The tangent is opposite over adjacent.
The angle of elevation is 63° to the nearest degree.
A line parallel to the x-axis is horizontal and thus any point on the line has a fixed y-coordinate. So the given line that passes through (-5, 4) has equation y = 4 with slope 0.
A line perpendicular to this one would be vertical. Its slope would be undefined (or infinite, depending on convention), so that any point on it has a fixed x-coordinate. If this line also passes through (-5, 4), then its equation would be x = -5.

Sure.

Answer:
the answer is 84.56
Step-by-step explanation:
A = lw
A = 18 · 4
A = 72
The area of the rectangle is 72 cm2.
Circle
A = πr2
A = 3.14(2)2
A = 3.14(4)
A = 12.56
The area of the circle is 12.56 cm2.
Find the area of the bookmark.
A = 72 + 12.56
A = 84.56
