Answer:
x = 7
Explanation:
Δ JUT is similar to Δ JKL (AA postulate ) , then the ratios of corresponding sides are in proportion, that is
=
( substitute values )
=
=
( cross- multiply )
8(- 4 + 4x) = 3 × 64 = 192 ( divide both sides by 8 )
- 4 + 4x = 24 ( add 4 to both sides )
4x = 28 ( divide both sides by 4 )
x = 7
