Angle B = ADC arc / 2
32 = ADC arc / 2
ADC arc = 2 × 32
ADC arc = 64
_________________________________
ADC arc + ABC arc = 360
64 + ABC arc = 360
ABC arc = 360 - 60 - 4
ABC arc = 300 - 4
ABC arc = 296
_________________________________
Angle D = ABC arc / 2
x = 296 / 2
x = 148
_________________________________
Angle A = x - 40
Angle A = 148 - 40
Angle A = 108 degrees
Answer:
4.25
Step-by-step explanation:
To find the scale factor divide the image coordinates by the original coordinates, that is
scale factor =
=
= 4.25
(30x7)+(7x5) you basically just have break it up.I hope this really helped you.
Answer:
<em>x = 2.93</em>
Step-by-step explanation:
The sum of angles of the triangle is 180degrees, hence;
9x - 72 + 73x + 11 = 180
82x - 61 = 180
82x = 180 + 61
82x = 241
Divide both sides by 82
82x/82 = 241/82
<em>x = 2.93</em>
