You have climbed to the top of a tall tree. When you get to the top, you use your clinometer to discover that the angle between
GuDViN [60]

Answer:

F. 34.64 m

Step-by-step explanation:

The measurements given in the question are;

The angle (of depression) given by the clinometer, θ = 30°

The horizontal distance of the lunchbox from the tree, d = 20 meters

The height (how tall) of the tree = Required

Let the height of the tree be assumed to be perpendicular to the ground, noting that the horizontal distance from the lunchbox to the tree is a straight line, let <em>l</em> represent the line of sight from the top of the tree to the lunchbox, and let <em>h </em>represent the height of the tree we have;

The line of sight to the lunchbox, <em>l</em>, the height of the tree, <em>h</em>, and the horizontal distance of the lunchbox from the base of the tree form a right triangle

The height of the tree is the adjacent leg to the given angle by the clinometer

Using trigonometric ratios, we have;

tan(30°) = d/h

∴ tan(30°) = (20 m)/h

h = (20 m)/tan(30°) ≈ 34.64m

The height of the tree, h ≈ 36.64 m.

Answer:

90, 90, 90, 135, 135

Step-by-step explanation:

The sum of the measures of all angles is 540 deg.

The measures of the angles are: x - 45, x - 45, x, x, x - 45.

Add the expressions of the measures of the angles and set equal to the sum of the measures, 540 deg. Then solve for x. Then use the value of x to find each angle measure.

x + x + x - 45 + x - 45 + x - 45 = 540

5x - 135 = 540

5x = 675

x = 135

x - 45 = 135 - 45 = 90

Answer: 90, 90, 90, 135, 135
