(Please can I get some help with this?) An airplane ascends at an angle of elevation 22 for a ground distance of 7850 feet. What height does the plain gain during this ascent?

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

there is no following? ! lol
