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
If the ratio is 1:18, and we need to know how the other side for the ration 9:?, then we have to multiply 9x18.
9x18=162
so Laurel and Delmar are 162 km away
hope it helps! :3
Answer: second one
Step-by-step explanation:
Answer:
x = -1 
Step-by-step explanation:
f(
) = 120, therefore we can create this equation:
120 = 150 ÷ ( - z)
cross-multiply to get: 24 - 120z = 150
-120z = 126
z = -1
