Answer:
The original height of the tree is 18 m.
Step-by-step explanation:
Please see attached photo for explanation.
From the diagram, we shall determine the value of 'x'. This can be obtained by using the pythagoras theory as follow:
x² = 5² + 12²
x² = 25 + 144
x² = 169
Take the square root of both side
x = √169
x = 13 m
Finally, we shall determine the original height of the tree. This can be obtained as follow.
From the question given above, the tree was broken from a height of 5 m from the ground which form a right angle triangle with x being the Hypothenus as illustrated in the diagram.
Thus, the original height of the will be the sum of 5 and x i.e
Height = 5 + x
x = 13 m
Height = 5 + 13
Height = 18 m
Therefore, the original height of the tree is 18 m.
Answer:
\left(\frac{\sqrt{78}}{30},\ \frac{\sqrt{78}}{39}\ ,\frac{41\sqrt{78}}{390}\right)
Answer:
f = 8
Step-by-step explanation:
9f = 8f + 8
9f - 8f
= f
So, f = 8
9(8) = 8(8) + 8
72 = 72
I think it's 79.50 square units. there three triangles in the quadrilateral shape above with the areas given so add the areas together to get the answer
A triangle's angle measures add up to 180°.
67 + 90 = 157
180 - 157 = 23
The last angle measure is 23°.
The longer the side length, the larger the angle opposite it is. And vice versa. The shorter the side length, the smaller the angle opposite it is.
Side Length: ∠ Measure Opposite Side:
5 in 23°
12 in 67°
13 in 90°
