Answer 1

do you have any idea ?

Answer 2

Since `RST is congruent to LMN` that would mean corresponding angles are congruent to each other. `LMN` seems to be flipped so `angle M is congruent to angle S`. `Angle R is congruent to angle L`. You would add the angles up and subtract it by the total degree of a triangle to find angle T.

Answer 3

If we can determine the measure of angle S we can determine the measure of angle T by sum of triangle theorem.
We can derive that angle S = 70 because Angle S = Angle M
So now we can find angle T
Angle T + Angle S + Angle R = 180
Angle T + 70 + 65 = 180
Angle T = 45

Answer 4

Okay I understand

Answer 5

Good.
