Answer: AB = 12.5, BC = 15
<u>Step-by-step explanation:</u>
Perimeter of ΔBCD = BC + CD + BD. Since it is an isoceles triangle, then BC = CD = BD. So, Perimeter of ΔBCD = 3BC
3BC = 45
<u>÷3 </u> <u>÷3 </u>
BC = 15
Perimeter of ΔABC = AB + BC + AC. Since it is an isosceles triangle with BC as the base, then AB = AC. So, Perimeter of ΔABC = 2AB + BC
2AB + BC = 40
2AB + 15 = 40
<u> -15</u> <u> -15 </u>
2AB = 25
<u>÷2 </u> <u>÷2 </u>
AB = 12.5
Answer:
<h2>Option A</h2>
Step-by-step explanation:
<h3>To round to ONE decimal place means one significant number should be after the decimal point (.)</h3><h3>Option A is the correct answer because if I a zero leads after the decimal point then it isn't significant.</h3><h3>The zero in option A is insignificant but other numbers are and it says to ONE decimal place so option A is the correct answer.</h3><h3>Hope this helps.</h3>
Good luck ✅.
Answer:
this is correct
Step-by-step explanation:
f continous in x=30 means that it should be the same value for 1.25 x 30 and 1.10 x 30 + k so k =4.5
