Answer:
Step-by-step explanation:
a² + b² = c²
a² + 9² = 12²
a² + 81 = 144
a² = 63
a = √63
The simplest answer form would be -5 square root of 7 end root + 7 square roots of 6
You can solve this by creating the equation 4x+14=60. Now all you have to do is solve this simple algebraic equation. How this helps:)
Answer:
E, F, A, ED, BC, EF, ABC, EDF
Step-by-step explanation:
The angle and side markings show which segments and angles are congruent.
We can make a table of corresponding pairs based on the number of marks:
marks, angle, side
- A and E, DF and BC
- B and D, ED and AB
- C and F, EF and AC
__
This can help us fill in the question numbers:
- ∠E is congruent to ∠A
- ∠F is congruent to ∠C
- ∠A is congruent to ∠E
- ED is congruent to AB
- BC is congruent to DF
- EF is congruent to AC
- 8. ΔABC ≅ ΔEDF
