Wendy is standing 60 feet away from a tree. Her eyes are 5 feet above the ground. She sees a bird hovering above a tree. The ang
andreev551 [17]

Answer:

a) The tree is 32.98 feet  tall.

b) The bird is 50.21 feet high in the air.

c) The Bird is 17.23 feet far above the Tree.

Step-by-step explanation:

From the attached diagram, please familiarize yourself with the statement drawn out and the points drawn out for better understanding.

Note that Line CD is the ground level and Line QE is the Wendy's eyes height.

1) <em>How tall is the tree</em> (Line BC)

line BC (tree height) => QC + QB

Line ED = QC,  ∴ QC = <em>5 ft</em>

Since <BEQ = 25° and CD = QE, ∴ QE = 60ft all in triangle BEQ

Therefore Tan 25° = BQ/60

BQ = 60 (0.4663)

BQ = <em>27.98 ft</em>

tree height => QC + QB = 5 ft + 27.98 ft ==> 32.98 ft

2) <em>How high is the bird in the air?</em> (Line AC)

line AC (bird height) => QC + QA

Line ED = QC,  ∴ QC = <em>5 ft</em>

Since <AEQ = 37° and CD = QE, ∴ QE = 60ft in triangle AEQ

Therefore Tan 37° = QA/60

QA = 60 (0.7536)

QA = <em>45.21 ft</em>

bird height => QC + QA = 5 ft + 45.21 ft ==> 50.21 ft

3) <em>How far above the tree is the bird?</em>

The difference between the bird height and the tree height = Line AC - Line BC

= 50.21 ft - 32.98 ft

= 17.23 ft

A child’s building set contains a brick with dimensions 63 x 31 x 18mm . Assume this brick is a replica of a real brick that has
TEA [102]

The surface area and volume of the real brick will be 983.2 cm²and 1738.11 cm³ respectively.

<h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The scale factor is ;

r = 630 cm /23

r = 27

L = 23 cm

b = 310 / 27 = 11.48 cm

h = 180/27 = 6.6 cm

The surface area of the brick;

A = 2(lb+bh+hl)

A = 2( 23 ×11.48+11.48×6.6+6.6×23)

A= 983.2 cm²

The volume of the brick is;

V= lbh

V=23 × 11.45 ×6.6

V=1738.11 cm³

Hence the surface area and volume of the real brick will be 983.2 cm² and 1738.11 cm³ respectively.
