Question

13)A tree is broken at a height of 5 m from the ground and its top touches the
ground at a distance of 12 m from the base of the tree. Find the original height
of the tree.​

Answer 1

Answer:

144- 25 119

Step-by-step explanation:

anewer 119

it is hypotenuse square=base +height square

Answer 2

Answer:

18m

Step-by-step explanation:

Using :

Formula for hypotenuse = a² + b² = $c^2$ [ a = side of right triangle, b = side of right triangle, c = hypotenuse ]

Using Pythagoras theorem, In ΔABC :

• $(AC) ^2 = (AB) ^2+(BC) ^2$
• $(AC) ^2=12 ^2+5 ^2$

• $(AC) ^2=144+25$

• $(AC) ^2 =169$
• AC    =  √169

• AC    =    13 m

Hence, the total height of the tree = AC+CB=13+5=18m.
