Answer:
∠ 1 = ∠ 2 = 75°
Step-by-step explanation:
The sum of the 3 angles in Δ CDE = 180°
sum the angles and equate to 180°
∠ 1 + 38° + 67° = 180°
∠ 1 + 105° = 180° ( subtract 105° from both sides )
∠ 1 = 75°
∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so
∠ 2 = 75°
Answer:
The sum of two numbers is 240. The larger number is 6 less than twice the smaller. Find the numbers.
----------
Let the smaller be "x" ; Larger is "2x-6"
EQUATION:
x + 2x-6 = 240
3x= 246
x = 82 (smaller)
2x-6 = 158 (larger)
Step-by-step explanation:
The price of gasoline in this week is 1.05g. Option C
