Answer: b) ΔADC ≡ ΔBCD by SAS
<u>Step-by-step explanation:</u>
Step 1: AD = BC SIDES are congruent
Step 2: ∠ADC ≡ ∠BCD ANGLES are congruent
Step 3: DC = DC SIDES are congruent
The proof is using Side-Angle-Side (SAS)
Look at the angles in step 2. These are the triangles you are proving congruency for: ΔADC ≡ ΔBCD
Answer:
y^2 - x^2 = 11
Step-by-step explanation:
y^2 - x^2 = ?
Substitute.
y = 6
x = 5
Becomes:
6^2 - 5^2 = ?
Solve.
6^2 = 6 x 6
6 x 6 = 36
5^2 = 5 x 5
5 x 5 = 25
36 - 25 = 11
Answer:3.9
