Determine if the two triangles are congruent

yes, ASA

Step-by-step explanation:

you know an angle. they share a side so that's congruent. on any line, the angles must add to 180, so if one is right so is the other. so those angles are also congruent. so you have two angles and a side that go in the order A,S,A. so it's ASA

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
