Answer:
Angle T = 28, h = 18
Explanation:
HW/ER = WT/RD Thales Theorem
10/5 = h/9 Substitution
2 = h/9 Alg
h = 18 Alg
Angle D = Angle T Similarity definition
Angle D + Angle E + Angle R = 180 Angle Sum Property
Angle D + 86 + 66 = 180 Substitution
Angle D + 152 = 180 Alg
Angle D = 28 Alg
Angle D = Angle T = 28 Similarity Definition
Hope this helped!
