Answer:
Hi. I don't know what your question is, but if you ask it, I'll try to answer it.
Step-by-step explanation:
If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
Answer:
10 ??
Step-by-step explanation:
Answer:
Corresponding side lengths and angle measures of two congruent triangles are also congruent.
Step-by-step explanation:
If two triangles ABC and DEF are congruent (see below figure) to each other then, AB=DE, BC=EF, AC=DF and <A=<D, <B=<E, <C=<F
It's 77.472 , but since you probably need too round it will be 77.5
