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:
3 + 2x + 1 = 2x + 3

Answer:
X > 43
Step-by-step explanation:
The inequality is given by :
X + 24 > 67
We need to solve the inequality.
Subtract 24 from both sides of the inequality.
X + 24 -24 > 67 - 24
X > 43
So, the solution of the inequality is more than 43.
Answer:
The markup percentage is 30.76 %
Step-by-step explanation:
Given as :
The selling price of an item = s.p = $650
The wholesale price of an item = w.p = $ 450
Let The markup percentage = d %
Now, According to question
d % =
Or, d =
× 100
Or, d = 
Or, d =
× 100
Or, d = 30.7 5
The markup percentage = d = 30.76 %
Hence The markup percentage is 30.76 % Answer
