State what additional information is required in order to know what the triangles are congruent by ASA

The answer to your question is  third choice ∠E ≅ ∠ R

Step-by-step explanation:

From the picture, we know that EF ≅ FR

And that                                       ∠EFG ≅ ∠RFT  (vertical angles)

So, we need to prove that another angle is congruent to prove ASA.

From the choices, the only possibility is the third answer   ∠E ≅ ∠ R.

Now, we have proof that ΔEFG ≅ ΔRFT

all but the second one

step-by-step explanation:

cuz that one goes over 180

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
