Answer: 51 feet
Since we know George's height, the length of George's shadow, and the length of the flagpole's shadow we have all the information we need
Now we can set up a relationship between George and the flagpole:
6 represents George's height
10 represents the length of George's shadow
x is the unknown height of the flagpole
85 is the length of the flagpole's shadow
Now you solve for x:
So, the height of the flagpole is 51 feet
Answer:
each card's thickness ×no of cards=total thickness
3/160×X=3/4
X=3/4×160/3
X=40
40 cards r in the stack
The answer is true. An altitude of a triangle is the perpendicular segment from a vertex to the line containing the opposite side.
First find the value of h, or the height using the pythagorean theorem.
13^2=15^2+h^2
289=225+h^2
h^2=64
h=8
Then use the formula bh/2 to find area of the triangle.
10*8/2=40
Final answer: A
