Answer:
x = 47°
Step-by-step explanation:
This is an exterior angle property, one of the properties in a triangle. The exterior angle theorem states that if a triangle's side gets an extension, then the resultant exterior angle would be equal to the sum of the two opposite interior angles of the triangle.
Answer:
1080°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 8, thus
sum = 180° × 6 = 1080°
Answer:
!. Scale factor = 5
2. Scale factor = 
Step-by-step explanation:
scale = 
1. To increase the numbers, let the scale factor be
= 5. So that;
0.05 x 5 = 0.25
x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be
. So that;
0.05 x
= 0.01
x
= 0.5 x
= 0.10
7 x
= 1.40
13 x
= 2.60
25 x
= 5.00
102 x
= 20.40
When x=-5, y=(1/5)*(-5)-1=-2, so the first order pair is (-5,-2)
when y=-1, -1=(1/5)x-1, (1/5)x=0, x=0, so the second ordered pair is (0, -1)
