Shtirlitz [24]

Answer:

easy peasy

Step-by-step explanation:

u see,

the height of the airplane from the ground is 314m

but with the tower's horizontal plane, it would be

=> altitude of aircraft - height of tower

=> 314 - 70 = 244 m

now in the ABC,

using the ratio of sine,

sin 16 = AB/AC

=> 0.275 = 244/AC

=> AC = 244/ 0.275

=> AC = 887.9...

=> AC = approx. 886 meters

BEST ANSWER EARNS BRAINLIEST!
Lady bird [3.3K]
Please mark brainliest 3 more to rankup.

so is how I would solve this is one corner at a time. Since these are all triangles you will solve the area of a corner and divide it by 2. Then you will have the area of a corner.

(7.5 x 5) /2= 18.75
(7.5 x 14) /2=52.5
Mirror this on the other side because they are the same on the other side and then add them all together

(18.75 x 2) + (52.5 x 2) = 142.5

Answer is A
142.5

HELP!!!<br> With working out... what’s the values of a b and c<br><br> (2x+1)(ax+b)=(6x^2-5x+c)
Lady bird [3.3K]

Answer:

Step-by-step explanation:

(2x + 1)(ax + b) = 6x² - 5x + c

Expand the left side and put that half into standard form:

2ax² + 2bx + ax + b = 6x² - 5x + c

2ax² + (2b + a)x + b = 6x² - 5x + c

So now look at the x terms. We have "2a" x² on left and 6 x² on right, so:

2a = 6

a = 3

Then look at the x terms, those coefficients will then be equal:

2b + a = -5

2b + 3 = -5

2b = -8

b = -4

and finally, then non-x terms are equal:

b = c

-4 = c

so:

a = 3, b = -4, c = -4
