Answer:
3. ΔABC ≅ ΔCDA. Reason: HL postulate
Step-by-step explanation:
The two triangles are right triangles (∠B ≅ ∠D = 90°) and one leg (BC, DA) and the hypotenuse (AC, CA) are shown to be congruent. So, the HL postulate applies. The only step needed is to refer to that postulate.
Step 3. ΔABC ≅ ΔCDA. Reason: HL postulate
Answer:
2(8x)+5(8)
8
Step-by-step explanation:
The computation of the number that should go to finished the expression is as follows:
Given that
Kali earns $ 8 per hour.
If she worked for n hours so it would be $8n
And she worked on both monday and tuesday for x hours
So, the x hour earning is $8x and for both days it would be $2 (8x)
In addition to this, she worked 5 hours on thursday
So her earnings on thursday is 5×8=40
So, the total earning for the week is
2(8x)+5(8)
