Answer: ∠ACB= 60°, ∠DCE= 65°, ∠BCD= 55°
Step-by-step explanation:
1) Since ΔABC is an equilateral, we know ∠ACB= 60°
2) Since we know ΔCDE is an isosceles, we know that ∠DCE= 1/2 (180-50), which is 65°
3) We can add the 2 angles and then subtract them from 180 degrees to get ∠BCD= 55°
Answer:
(4) → (1) → (3) → (2)
Step-by-step explanation:
Order of operations in any question are decided by the rule,
P → Parentheses
E → Exponents
D → Division
M → Multiplication
A → Addition
S → Subtract
Following the same rule order of operations will be,
- Take care of anything inside the parentheses.
- Evaluate and raise the exponents
- Multiply or divide. Make sure to do whichever one comes first from left to right.
- Add or Subtract from left to right.
Options are arranged in the order of,
(4) → (1) → (3) → (2)

Answer:
None
Step-by-step explanation:
In order for lines to be parallel, their slope (m) must be equal.
0.03
Step-by-step explanation:
S ∝ t, introduce constant, if value of S depends on t only. Let that constant be 'k'.
=> S = kt
When, S = 0.6 & t = 4:
Answer
=> 0.6 = k(4)
=> 0.6/4 = k
=> 0.15 = k
Therefore, when t = 0.2
=> S = kt
= (0.15)(0.2)
= 0.03
