Hello!
So a tangent line is perpendicular to the radius, which means it creates a 90 degree angle with the radius of the circle. The sum of the interior angles of any triangle is 180 degrees. To determine if line BC is a tangent line, we have to determine if angle ABC is 90 degrees. Well we know the degrees of the other two angles of the triangle, so let's set up an equation:
180 = 48 + 47 + x
180 = 95 + x
85 = x
Since angle ABC must be 85 degrees (not 90), line BC is not a tangent line.
Answer:
<span>BC←→ is not a tangent line because m∠ABC ≠ 90°.</span>

7×8.75= 61.25 for 7 days
Formula for coordinates of midpoint,
x= (x1+x2)/2
y=(y1+y2)/2,
where (x1,y1), (x2,y2) coordinates of the end-points.
-1=(x1-8)/2
-2=x1-8
x1=-2+8
x1=6
1=(y1+4)/2
2=y1+4
y1=2-4
y1= - 2

Answer:
Flip the triangle
Step-by-step explanation:
Flip the triangle upside down over the red line. Hope it helps!!!
Answer:
26: 120
27: 56
Step-by-step explanation:
For 27 it is just the vertical angle of 56 degrease, so it is 56.
For 26 you can find the angle in between 80 and 60 by subtraction that amount from 180 because it is a straight line. You will get 40. X is the vertical angle of 80 and 40, which is 120, so x is 120.
