Question

Whats the heights and cm of the three triangles

Answer 1

For 1st triangle value of BC side =9CM

For 2nd triangle value of EF side =6FT

For 3rd triangle value of CE side=13.03YD

Using Pythagorean theorem which gives the formula of deriving Hypotenuse in an equilateral triangle.

Formula

c²= a² + b²

using this formula

AB= 12CM

BC=xCM

AC=15CM

AC²= AB² + BC²

BC²= AC²-AB²

x²CM= 225CM - 144CM

X²= 81CM

X=9 CM

Similarly

EF²= GE² - GF²

x²FT= 100FT - 64FT

x²= 36 FT

x= 6FT

For the last

CE² YD= CD² YD + CE² YD

x² YD= 49 YD + 121 YD

x² YD= 170 YD

x YD= 13.03 YD
