Answer:

3) Angle plus the angle will be the sum of the line making it 180 degrees.

4) X being the missing variable number to solve the final product of 180 with both angles missing a variable number. With angle 1 being 11x-6 and angle 2 being 4x+21

5) This is the after work when 11x and 4x was combined giving 15x and 21 and -6 combined giving 15 which combines both angles helping to find the sum in which will be 180

6) The after work, after 180 was subtracted with 15 giving it 165

7) The after work, after 165 was divided by 15 giving it 11, with 11 being the missing value of x

A tree broken at a height of 5 cm from the ground and it's top touches the ground at a distance of 12 m from base of the tree fi
Harrizon [31]

Answer:

The original height of tree is 18 m.

Step-by-step explanation:

Consider the correct question is "A tree is broken at the height of 5m from the ground and its top touches the ground at a distance of 12m from the Base of the tree. Find the original height of the tree."

A tree is broken at the height of 5m from the ground.

Let the height of the tree is (x+5) m.

After broken, it will form a right angle triangle with hypotenuse x, base 12m and perpendicular 5 m.

Using Pythagoras theorem,

hypotenuse^2=base^2+perpendicular^2

x^2=12^2+5^2

x^2=144+25

x^2=169

Taking square root on both sides.

x=13

Height of tree = x+5=13+5=18\text{ m}

Hence, the height of tree is 18 m.
