In an isosceles triangle the congruent sides each measure 25 yards and the base measures 30 yards what is the height of the tria

andrew11 [14]

Answer:

20 yards

Step-by-step explanation:

Since it is an isosceles triangle, a perpendicular from it's peak to the base bisects the base.

30/2=15

So using the Pythagorean theorem, hypotenuse^2=base^2+height^2

25^2=15^2+H^2

625=225+H^2

H^2=400

height=20 yards

<u>1st sector</u>:

$\sf \rightarrow area: \dfrac{80}{360} \pi (8)^2 = 44.68 \ cm^2$

<u>2nd sector</u>:

$\sf \rightarrow area: \dfrac{160}{360} \pi (4)^2 = 22.34 \ cm^2$
