So the plane of Olivia travels from west to east with an elevation of 6.3 km. To summarize everything and to get the speed of the plane, I used the Angle Side Angle Triangle Theorem and also the law of sine and the formula would be the following:
First is to get the distance traveled by the plane within the range of 3 minutes. To get that distance you must get the following variable.
total distance = distance travel from west to Todds position + distance traveled from Todds position to the reach of the elevation
Dt = D1 + D2
first is getting the D1
D1 = sin41 (6.3) / sin 49
(by following the law of sine and the angles is based on the triangle)
D1 = 5.477 km
then get D2,
D2 = 6.3 sin 65 / sin 25
D2 = 13.510
After that get the total distance
Dt = D1 + D2
Dt = 18.987 km
To get the speed of the plane, you must divide the distance to the time (in minutes) then multiply it by 60 to make it as an hour.
Speed = 18.987 /3 * 60 = 379.74 km/hr
The correct answer would be D, because there’s no other leading common factors between the two besides one.
6x+3=18
subtract 3 from both sides
6x=15
divide both sides by 6
x=2.5
5(4x-5)=155
distribute the 5
20x-25=155
add 25 to both sides
20x=180
divide both sides by 20
x=9
3x+(1/3)
Step-by-step explanation:
because 6b=2 you divide both sides by 6 and get 2/6 which can simplify to 1/3 =b
Adjacent sides of a parallelogram are not congruent.

Quadrilateral</h3>
A quadrilateral is a polygon with four sides and and four angles. A parallelogram has opposite sides parallel and equal. Two consecutive angles of a parallelogram are supplementary. Opposite angles and diagonals are congruent. The diagonals bisect each other.
(2x + 7) + (3x - 2) = 180 (consecutive angles)
x = 35°
