Answer:

Area = 97.4 cm²

Step-by-step explanation:

a = 15 cm

$Area = \frac{ \sqrt 3}{4} a^2\\$

$=\frac{\sqrt 3}{ 4 } \times 15^2\\\\=\frac{\sqrt 3}{ 4 } \times 225\\\\= 97.4 \ cm^2$

<h2>Range of x </h2><h3> $-\frac{1}{5}$ and x>6</h3><h3>Step-by-step explanation:</h3>

Given AB = 4x + 5, BC = 3x - 2 and AC 9x -5

The sum of the length of any two sides of a triangle is greater than the length of third side.

Case I

AB + BC > AC

⇔4x +5 +3x -2 > 9x -5

⇔7x + 3 >9x - 5

⇔ 7x -9x > -5 -3

⇔-2x > -8

⇔x <4

Case II

if AB+AC > BC

4x +5 +9x -5> 3x -2

⇔13x >3x -2

⇔ 13x -3x> -2

⇔10x > -2

⇔x > $-\frac{1}{5}$

Case III

AC+BC > AB

⇔9x - 5 +3x - 2 > 4x +5

⇔6x -7 > 4x +5

⇔6x -4x >5+7

⇔2x > 12

⇔x > 6

Eighth grade ) T.5 Pythagorean theorem: word problems 87U

Komok [63]

Answer:

The tree is 12 feet tall

Step-by-step explanation:

Let a represent the length of where the bird was sitting to the oak tree

let b represent the height of the tree

let c represent the length at which the bird flew

by pythagoras theorem

c²=a²+b²

b²=c²-a²

$b = \sqrt{ {c}^{2} - {a}^{2} }$

subtitute in the values

$b = \sqrt{ {15}^{2} - {9}^{2} }$

$b = \sqrt{225 - 81}$

$b = \sqrt{144}$

$b = 12$
