Answer:
x = 15
Explanation:
As we can see it is an isosceles triangle so
The perpendicular line joining the vertex and base of isosceles triangle bisects the base. so
Taking the triangle of right side
hypotenuse (h) = 25 inches
base (b) = 20 inches
perpendicular (p) = x = ?
We know by using Pythagoras theorem
p= √h² - b²
x = √ 25² - 20²
= √ 225
x =15
Hope it will help :)
