Step-by-step explanation:
We know sum of all angles of triangle is equal to 180°
4x + 3° + 8x + 6° + 2x + 17° = 180°
14x + 26° = 180°
14x = 180° - 26°
14x = 154°
x = 154°/ 14
Therefore x = 11°
Now
<T = 4 * 11° + 3° = 47°
<U = 2* 11° + 17° = 39°
<V = 8* 11° + 6° = 94°

12. ∆ABD is similar to ∆PQD, so
QD/z = BD/x
Likewise ∆CDB is similar to ∆PQB, so
QB/z = BD/y
Since QD + QB = BD, you have
QD/z + QB/z = BD/x + BD/y
BD/z = BD/x + BD/y
Dividing by BD gives the desired result:
1/x + 1/y = 1/z
13. Triangles ABD, BCD, and ACB are all similar. This means
AB/AC = AD/AB
AB² = AC×AD = (4 cm)×(9 cm)
AB² = 36 cm²
AB = 6 cm
and
BD/CD = AD/BD
BD² = CD×AD = (5 cm)×(4 cm)
BD² = 20 cm²
BD = 2√5 cm
