Use the diagram and given information to answer the questions and prove the statement.

kiruha [24]

Answer:

See explanation

Step-by-step explanation:

Consider triangles BXY and AZY. In these triangles:

$\angle X\cong \angle Z$ - given;
$\overline{XY}\cong \overline{ZY}$ - given;
$\angle XYZ\cong \angle ZYA$ as right angles by reflective property.

Hence, $\triangle BXY\cong \triangle AZY$ by ASA postulate (or by LA postulate).

Congruent triangles have congruent corresponding sides, so

$\overline{XB}\cong \overline{ZA}$

Solve for x . 3(2 x - 3) + 4(2 - x ) = 0 17/10 -17/10 1/2

fiasKO [112]

Answer:

x = $\frac{1}{2}$

Step-by-step explanation:

3(2x - 3) + 4(2 - x) = 0 ← distribute parenthesis

6x - 9 + 8 - 4x = 0 , that is

2x - 1 = 0 ( add 1 to both sides )

2x = 1 ( divide both sides by 2 )

x = $\frac{1}{2}$
