**Answer:**

2*2*2*2*2*2=64

**Step-by-step explanation:**

please mark brainiest hope it works out for you

We have to determine the congruence criteria which would prove that the given triangles are congruent.

Consider the triangles RSV and VTU

VR = VU (Given)

(Given)

(Given)

Hence, the triangles RSV and VTU are congruent by AAS congruence criteria.

**As, if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent by AAS congruence criteria.**

So, option 4 is the correct answer.

Combine like terms so add 4b and 15b together and add 7 and 3 together and then the answer would be 19b-10
