If we have two similar triangles:
Triangle 1 (base 1 , height1).
Triangle 2 (base 2, height 2)
Then:
base 1 /height 1=base 2 /height 2
Data:
base 1=0.2 m
height 1= 1 m
base 2= 8 m
height 2=x
We calculate the height of the tower:
base 1 /height 1=base 2 /height 2
0.2 m / 1m=8 m / x
x=(8 m * 1 m) / 0.2 m
x=8 m²/0.2 m
x=40 m
Answer. the heigth of the tower will 40 m
Answer:
this answer is perfect I hope enjoy it
Answer:
x = 3
Step-by-step explanation:
Given
5x - 3 = 12 ( add 3 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
As a check
Substitute x = 3 into the left side of the equation and if equal to the right side then it is a solution.
5(3) - 3 = 15 - 3 = 12 = right side
Thus x = 3 is the solution
Corresponding angles postulate, as the two 35 degree angles are corresponding.
