Answer 1

Hey mate,
Here's the solution to ur question!!!!

Hope it helps!!!

Answer 2

both the questions can be solved by Pythagoras theorem.
1)) height of the ladder=17m
base=8m
we should find the height of the wall.
. let us assume it as triangle ABC.
AB is the height of wall=?
BC is the base=8m
and AC is the height of the ladder=17m
By Pythagoras,
AC^2=AB^2+BC^2.
we need to find AB,we will exchange the terms.
AB^2=AC^2 - BC^2.
AB^2=(17)^2 - (8)^2
AB^2= 289 - 64
AB^2= 225
AB=√225
AB=15m.
therefore, height of the wall is 15m..

2)) similarly just like the first question.
height of the ladder=AC=25m
height of the wall=AB=20m
base =BC=?
by Pythagoras,
AC^2=AB^2 + BC^2
AC^2 - AB^2 =BC^2
625- 400=BC^2
225=BC^2
BC=√225
BC=15m.
therefore, base =15m.
