Step-by-step explanation:

Let's setup a proportion to find AB.

AB corresponds to A'B'.

BC corresponds to B'C'.

So setting up proportion this would look like:

[\tex]\frac{AB}{A'B'}=\frac{BC}{B'C'}[/tex]

[\tex]\frac{AB}{15}=\frac{3.8}{9.5}[/tex]

Cross multiply:

AB(9.5)=15(3.8)

Divide both sides by 9.5:

$AB=\frac{15(3.8)}{9.5)}$

Put into calculator:

AB=6

AB=6 so A is correct, hope this help! Branliest would be awesome :)

Step-by-step explanation:

Since the larger rectangle and the smaller rectangle are essentially the same just bigger, they will be proportionate.

Therefore..

9.5/3.8=15/AB

You can cross multiply to find AB...

9.5AB=57

Divide 57 by 9.5 to separate AB, which you can think of like x...

AB=57/9.5

AB=6

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.
