Answer:
2. ΔABC is isosceles
Step-by-step explanation:
Given : m∠A = 50
m∠BCD = 180 - (m∠BDC + m∠DBC)
= 180 - (100 + 30)
= 50
then
m∠A = m∠BCD
therefore ΔABC is isosceles
Answer:
Step-by-step explanation:
- A. 134 is the mode, correct, repeated 5 times
- B. 111 is appears 3 times, incorrect , this number is not part of data set
- C. There are more data values between 130 and 139, correct, there are 8 of them

Step-by-step explanation:
-5/8, -1⅔, 0.8, ½
-5/8 = -0.625
-1⅔ is approximately -1.67
0.8
½ = 0.5
-1.67, -0.625, 0.5, 0.8
-1⅔, -⅝, ½, 0.8
