A hot-air balloon is floating above a straight road. To calculate their height above the ground, the balloonists simultaneously measure the angle of depression to two consecutive mileposts on the road on the same side of the balloon. The angles of depression are found to be 18∘ and 22∘. How high (in feet) is the ballon?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16

c.the first excerpt shows their expectations about the camp, and the second shows the reality of their circumstances

is the answer this is because first they talk about what is expected of the camp but in the second excerpt they get a harsh awakening to the true realities of the camp.

hope this

i would appreciate brainliest : )
