m∠ACB = 180° - 58° - 78° = 44°
m∠DCE = 180° - 85° - 60° = 35°
m∠BCD = 180° - 44° - 35° = 101°

Base on the picture, we know that:
x° + 2x° + 3x° = 180°
6x° = 180°
x° = 180° ÷ 6 = 30°
=> m∠K = 2x° = 2 × 30° = 60°
=> m∠L = 3x° = 3 × 30° = 90°
=> m∠KML = x° = 30°
m∠LMN = 60° + 90° = 150°
Answer:
Step-by-step explanation:
To start with we can consider how many possibilities there are for the first card which is obviously 52, as any one of the cards in the deck can be found on the top of the pile. The next card is a bit trickier as there are only 51 possible cards that it could be as the first card takes up a spot. The third card now only has 50 possible cards it could and this continues all the way down to the last card.
is that good
Answer:
189
Step-by-step explanation:
Since the series is geometric with common ratio r, then
r = 6 ÷ 3 = 2
The terms in the series are twice the previous term, that is the series is
3 + 6 + 12 + 24 + 48 + 96 ← summing the terms gives
sum = 189
Answer:
C
Step-by-step explanation:
Black = 200 x 0.19 = 38
White = 200 x 0.12 = 24
We know that a straight line is 180⁰ and inside angle is given 110°.
180°-110° = 70°
x=70°
