Answer:

  x = 12

Step-by-step explanation:

The sum of the exterior angles of a convex polygon is 360°.

  (5x +4)° +(4x +9)° +(9x -6)° +(4x +1)° +(7x +4)° = 360°

  29x +12 = 360 . . . . . divide by °, collect terms

  29x = 348 . . . . . . . subtract 12

  x = 12 . . . . . . . . . divide by 29

Answer:

x=11.58

Step-by-step explanation:

The sum of an exterior angle of a polygon is 360°,

9x-6+4x+9+5x+4+7x+4+4x+1=360°

29x+24=360

29x=360-24

29x=336

x=336/29

x= 11.586

x=11.58

Hope it helps! :)

Write an explicit formula for the sequence 7, 1, -5, -11, -17,... Then find a14
Oksana_A [137]
An=a1+d (n-1)
a1= 7
find d
Let's use a2
a2=1
1=7+d (2-1)
1=7+d
-7 both sides
d=-6
explicit formula is

an=7+-6 (n-1)

a14=?
a14=7-6 (14-1)
a14=7-6×13
a14=7-78
a14=-71

it can be -8 or 90

you should specify which one is t1 and which one is t2

Step-by-step explanation:

2( {2})^{2}  + 8( - 5) + 24 =  - 8

Mai is flying a plane at an altitude of 1600 ft. She sights a stadium at an angle of
LekaFEV [45]

Answer:

2,789ft

Step-by-step explanation:

The set up will give a right angled triangle.

The altitude will be the opposite side = 1600 ft

The angle of depression = 35°

approximate direct distance to the stadium is the hypotenuse of the trisngle= x

Using the SOH trig identity to get the distance

sin 35 = opp/hyp

sin 35 = 1600/x

x = 1600/sin35

x = 1600/0.5736

x = 2,789.4ft

Hence mai’s approximate direct distance to the stadium is 2,789ft
