Which of the following proves trinagle ABC =~ trinagle DEF? Please help me step-by-step with this please, and if you give just a
straight answer with no proof then Ima just assume that you are here answering incorrectly and are just here for the points!!

Answer:
C. ASA
Step-by-step explanation:
The details of the given parameters are;
Angle ∠B of ΔABC is congruent to angle ∠E of triangle ΔDEF,
Angle ∠C of ΔABC is congruent to angle ∠F of triangle ΔDEF
Side of ΔABC is congruent to side
of triangle ΔDEF
Two angles (∠B and ∠C) and the included side (side ) of ΔABC are congruent to the corresponding two angles and included side (∠D, ∠E and side
) of ΔDEF, therefore, the two triangles are congruent by the Angle-Side-Angle, ASA, rule of congruency

Answer:
tanI =
Step-by-step explanation:
We require to calculate GH using Pythagoras' identity in the right triangle.
GH² + GI² = HI²
GH² + 5² = ( )²
GH² + 25 = 95 ( subtract 25 from both sides )
GH² = 70 ( take square root of both sides )
GH =
Then
tanI = =
=
