Answer:
5
Step-by-step explanation:
because there is a perfect triangle ratio thing that is 1: 1: √(2)
Short Answer Only B is true.
Reasoning
A
A is not True. CBG is not equal to DBG. They are supplementary but not equal.
B
B is correct.
C
CBG = DBF are given as equal. It is not necessarily true that they are supplementary. That would be true only if they were both 90o
D
The two angles are equal, but they are not supplementary. They would be only if both were 90o which is shown not to be the case.
Answer:
Therefore the height of the tower is 116.75 m.
Step-by-step explanation:
Given that a pole that is 2.6 m tall casts a shadow that is 1.03 m long.
Here the height of a object directly proportional to the shadow. It means
Height of the object ∝ shadow
Height of the object= k.shadow
[k is the proportional constant.]
[Height of object is denoted by h and shadow is denoted by s]
Then,
[h₁ is the height of the pole and s₁is the length of the shadow]
Again for the tower
[h₂ is the height of the tower and s₂ is the length of the shadow]
Therefore,
![\frac{h_1}{s_1}=\frac{h_2}{s_2} =k](https://tex.z-dn.net/?f=%5Cfrac%7Bh_1%7D%7Bs_1%7D%3D%5Cfrac%7Bh_2%7D%7Bs_2%7D%20%3Dk)

Putting the value of

equation (1)
![\frac{2.6}{1.03}=\frac{h_2}{46.25}](https://tex.z-dn.net/?f=%5Cfrac%7B2.6%7D%7B1.03%7D%3D%5Cfrac%7Bh_2%7D%7B46.25%7D)
[cross multiplication]
![\Rightarrow h_2 = \frac{2.6\times 46.25}{1.03}](https://tex.z-dn.net/?f=%5CRightarrow%20h_2%20%3D%20%5Cfrac%7B2.6%5Ctimes%2046.25%7D%7B1.03%7D)
![\Rightarrow h_2= 116.75](https://tex.z-dn.net/?f=%5CRightarrow%20h_2%3D%20116.75)
Therefore the height of the tower is 116.75 m.
The answer is D. This is because the longest side length cannot be equal to or longer than the other 2 sides added together.
The longest side is 6, and the other two are 2 and 3.
2+3=5
6>5.
6 is greater than 5, therefore, this cannot be the lengths of a triangle.
Answer:
29 16/25
Step-by-step explanation:
29 and 64/100
reduces to 29 16/25
