Answer: mâ E = 60°
Step-by-step explanation:
Here, ABC and DEF are two triangles in which,
mâ A = 90°, mâ B = 60° and mâ C = 30°
Also, Î ABC â Î DEF
Thus, By CPCTC ( congruent part of congruent triangles are congruent )
mâ A = mâ D = 90°
mâ B = mâ E = 60°
mâ C = mâ F = 30°
Hence, the measurement of angle E is 60 degree.
