Question

The figure below shows a triangular lawn labeled PQR. There are two fences, AB and BC.

What is the total length of the fence AB and BC?
Answer 90 feet
130 feet
160 feet
200 feet

Answer 1

Figure please !

Answer 2

im so sorry i forgot

Answer 3

No problem.

Now Your task must be to prove the triangle PAB and PRQ must be similar triangles. Then take ratio of corresponfing sides and get your answer. If you don't follow, Have a look at similar triangles in mathematics :)

Answer 4

*corresponding

Answer 5

is it 90

Answer 6

no 130

Answer 7

PB/PQ = AB/RQ

AB = 40

Answer 8

Similarly try the other one :)

Answer 9

im con fused i would think it had to be 90 or 130 but its way smaller so im actually thinking 90

Answer 10

Well, thinking won't match with your answers in math most of the time. Apply your math correctly at it should be alright. The diagram you are seeing is not actually to scale. If you apply the math, you should get

PB/PQ = AB/RQ

AB = 40

Well, if you trust your instincts more, sorry, I can't help you :)

Answer 11

its not that i dont trust my instincts im just confuse
