Answer:
1. ΔABC is a right triangle, with a right angle at ∠C. ~ Given
2. Draw an altitude from point C to (line segment) AB ~ From a point not on a line, exactly one perpendicular can be draw through the point to the line.
3. ∠CDB and ∠CDA are right angles ~ Definition of altitude
4. ∠BCA ≅ ∠BDC ~ All right angles are congruent
5. ∠B ≅ ∠B ~ Reflexive Property
6. ΔCBA ~ ΔDBC ~ AA Similarity Postulate
7. a/x = c/a ~ Polygon Similarity Postulate
8. a^2 = cx ~ Cross Multiply and Simplify
9. ∠CDA ≅ ∠BCA ~ All Right Angles are Congruent
10. ∠A ≅ ∠A ~ Reflexive Property
11. ΔCBA ~ ΔDBA ~ AA Similarity Postulate

Answer:
The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. The mode is the value that occurs most often.
Solve for g:
2 g = 9 - 7 g
Add 7 g to both sides:
2 g + 7 g = (7 g - 7 g) + 9
7 g - 7 g = 0:
2 g + 7 g = 9
2 g + 7 g = 9 g:
9 g = 9
Divide both sides of 9 g = 9 by 9:
(9 g)/9 = 9/9
9/9 = 1:
g = 9/9
9/9 = 1:
Answer: g = 1
I believe the Answer is : 12/13
