Answer 1

$\large{\mathtt{\red{\underbrace{\overbrace{\blue{\boxed{\boxed{\pink{«Answer»}}}}}}}}}$

Height of House = 25 feet

Distance on ground = 10 feet

Since it is forming a right angle triangle

Therefore, we can say

x² = 25²+10²

x² = 625+100

x² = 725

x = √725 feet

or

x = 27 feet (approx)
