The distance between the helicopter and the first home is 369. 87 m
<h3>How to solve the distance using the angle of depression?</h3>
The distance between the helicopter and the first home can be found using sine law,
Therefore,
180 - 72 - 49 = 59 degrees.
Hence,
420 / sin 59 = A / sin 49°
where
A = distance form the first home to the helicopter.
cross multiply
420 sin 49 = A sin 59°
A = 420 sin 49 / sin 59
A = 316.978023694 / 0.8571673007
A = 369.869339199
A = 369. 87 m

5x-2 this is the equation
Answer:
The answer is 1…
Step-by-step explanation:
Well you can elimate a lot of fractions right off the bat just multiply everything by 60/1.
the final result will be
(240+15+40)+ (300+90-72)- (360+105+24)
Now solve
240-15+40=265
300+90-72=318
360+105+24=513
265+268-489
265+268= 11
533-513=20
bleh i m not sure naymore
Answer:
There are 3 angles on a straight line : WYX, WYV, VYZ
now,
given, (WYV = 6x - 12) , (VYZ = x + 16) ,
(WYX = VYZ) { They are opposite angles}
.
Sum of all the angles will be 180°
WYX + WYV + VYZ = 180°
(6x - 12) + (x + 16) + (x + 16) = 180°
6x - 12 + 2x + 32 = 180°
8x + 20 = 180°
8x = 180° - 20°
8x = 160°
x = 160°/8 = 20°
now,
put the value of 'x' in WYV i.e. (6x - 12) = (6*20 - 12) ° = (120 - 12) ° = 108°
hence, WYV = 108°
