The diagram below shows an aircraft spotted by two observers who are 1000 feet apart. As the airplane passes over, Observer A takes a sighting of their angle of elevation to the plane. Observer A's angle of elevation is 40o. Find the missing measurements indicated below. Round each answer to the nearest hundredth where applicable. Type angles as whole numbers.

answer: (1,3) (3,-1) (5,-5) ?

step-by-step explanation:

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21

hope it

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
