Answer:
114°
Step-by-step explanation:
First we have to calculate the value of c Then
3c - 84° + c = 180° <being co-interior angles >
4c - 84° = 180°
4c = 180° + 84
4c = 264°
c = 264° / 4
c = 66°
Now
<R = 3 * 66° - 84°
= 114°
<P = <R ( being opposite angles of rhombus )
<P = 114°
Hope it will help :)
Answer:
♀️ i think if its a positive make it a negative and a negative make it a positive
900,000=10*90,000
So there are 90,000 tens in 900,000.
Speed, S = Distance (d) / Time (t) => S= d/t => t= d/S
Let the speed of boat in still water be x mph
Resulting speed upstream = x-4 mph for a distance of 30 miles
Resulting speed downstream = x-4 mph for a distance of 50 miles
Time taken in both distances is equal.
Therefore,
30/(x-4) = 50/(x+4) => 30(x+4) = 50(x-4) => 30x+120 = 50x-200 => 120+200 = (50-30)x => 20x = 320 => x=320/20 = 16 mph
The speed of boat in still water is 16 mph.
Answer:
g(-2) = -7
Step-by-step explanation:
To find g(-2), plug -2 into g(x).
g(x) = -4x² + 3x + 15
g(-2) = -4(-2)² + 3(-2) + 15
g(-2) = -4(4) + 3(-2) + 15
g(-2) = -16 + (-6) + 15
g(-2) = -1 + (-6)
g(-2) = -7
