2,916 is going to be your answer, they were all multiplied by 3 hope this helps!
Three diagonals can be drawn in a hexagon mmyyy dude.
2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
Answer:
b = 110°
Step-by-step explanation:
The sum of angles in a trapezoid is 360°
Summing the angles we get:
65°+55°+130°=250°
Then subtracting this value from 360° we get:
360°-250°=110°
Final answer of 110°
Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
