Here are two right angles. one pair of corresponding sides is marked congruent.

ASA congruence theorem

Step-by-step explanation:

WE know by given that ∠S ≅∠U and line ST ≅ line UT

By the vertical angles theorem, we can find that ∠RTS ≅ ∠VTU.

They are in a form that when looking around the edge, you see congruent angle, side, then angle. That means that we can prove the triangles' congruence with ASA congruence.

i think it would be 42cm

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
