ATUV is isosceles, with LT = LV and mU = 54°. What is m/T? (1 point)
0 m/T = 54°
0 mLT = 126°
0 mLT = 63°
0 mLT = 36°
Since ATUV is isosceles, LT = LV, we can use the fact that the sum of the interior angles of a triangle is 180°.
We know that mU = 54°, so if LT = LV, then mLT + mLV + mU = 180°.
Since LT = LV, we can substitute mLT for mLV, so we have:
mLT + mLT + mU = 180°
2mLT + mU = 180°
Substituting mU = 54°, we have:
2mLT + 54° = 180°
Solving for mLT:
2mLT = 126°
mLT = 63°
Therefore, m/T = mLT = 63°.
