In the figure below, triangle abc is similar to triangle pqr, as shown below: a right triangle abc with right angle at b and base bc is drawn. length of ab is 16, length of bc is 20. a similar right triangle; triangle pqr, which is triangle abc enlarged and reflected across a horizontal line, is drawn near it. the right angle is at q. angle a is congruent to angle p and angle c is congruent to angle r. the length of qr is 80. what is the length of side pq?

The length of the side PQ using the principle of similar triangle is 64

Using the principle of similar triangles, we can set up an expression thus :

Hence, we have ;

16/20 = PQ/80

cross multiply

20 × PQ = 16 × 80

20 × PQ = 1280

PQ = 1280 / 20

PQ = 64

Therefore, the value of PQ will be 64.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
