three significant figures.
the house and the hypotenuse of a right-angled triangle is 4:5. and the​

Answer 1

Step-by-step explanation:

Area of an equilateral triangle =√3/4xside²

Here,

____________

side=. / 25√3 X 4

√ √3

=√25x4(√3 will cancel out with denominator)

=√100

=10m²

Perimeter of the triangle,

=side x 3

=10×3

=30m²

In that figure,

AOB or AOC = hy²=p²+b²

=10²=p²+5²

=p =√10²-5²

=p=√100-25

=p=√75

=p=8.66
