David drew pqr and stu so that p s, pr = 12, su = 3, pq = 20, and st = 5. are pqr and stu similar? if so, identify the similarity postulate or theorem that applies.

Step-by-step explanation:

In the figure attached there are two triangle PQR and STU have been given.

We have to prove both the triangle are similar.

If these two triangles will be similar if corresponding sides should have the same ratio.

4 = 4

Hence the given triangles are similar

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
