tino4ka555 [31]

Answer:

The height of the triangle is 5.2 inches

Step-by-step explanation:

we know that

An <u>equiangular triangle</u> is a triangle where all three interior angles are equal in measure

Remember that an equilateral triangle has three equal sides and three equal interior angles

An equiangular triangle Is the same that an equilateral triangle. The measure of its interior angles is equal to 60 degrees

Let

h ----> the height of triangle

b ---> the length side of the triangle

Applying Pythagoras Theorem

$h^2=b^2-(b/2)^2$

we have

$b=6\ in$

substitute

$h^2=6^2-(6/2)^2$

$h^2=36-9$

$h^2=27$

$h=\sqrt{27}\ in$

$h=5.2\ in$

Giving the following information:

Number of students= 4,512

Declining rate= 2.5%

<u>To calculate the number of students next year, we need to use the following formula:</u>

Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)

x= number of years

Number of students(n1)= 4,512/1.025

Number of students(n1)= 4,402
