What is the missing statement in the proof? Scroll down to see the entire proof.

Eva8 [605]

Answer: C. $\angle BCA\cong \angle DCB$ is the missing statement.

Explanation: Given: ΔABC with m∠ABC = 90° (view diagram)

Prove: $AB^2 + BC^2 = AC^2$

Proof: 1. Draw $BD\perp AC$ (construction)

2. $\angle ABC\cong\angle BDC$ (Angles with the same measure are congruent.)

3. $\angle BCA\cong \angle DCB$ (Reflexive Property of Congruence)

4. $\triangle ABC\sim \triangle BDC$ (AA criterion for similarity)

5. BC:DC=AC:BC (Corresponding sides of similar triangles are proportional.)

6. $BC^2= AC\times DC$ (cross multiplication)----------(1)

7. $\angle ABC\cong \angle ADB$ (Angles with the same measure are congruent)

8. $\angle BAC\cong \angle DAB$ (Reflexive Property of Congruence)

9. $\triangle ABC\sim \triangle ADB$ (AA criterion for similarity)

10. AB:AD=AC:AB⇒ $AB^2=AC.AD$ --------------(2)

equation (1) + equation (2) ⇒ $AB^2+BC^2= AC(DC+AD)$ ⇒ $AB^2+BC^2= AC^2$

In a school with 400 students, 120 ride the bus to school. What percent of the students ride the bus to school

Murrr4er [49]

30% you have to find a equivalent number with the denominated 100z multiply both numerator and denominator by 100. 120/400x100/100= (120 x 100/400) x 1/ 100=30
