Answer:

7) No

8) Yes

Step-by-step explanation:

Tangent lines are perpendicular to the radius lines at the point of intersection. So we just need to check if these are right triangles.

7) c² = a² + b²

20² = 12² + 14²

400 = 340

8) c² = a² + b²

13² = 7.8² + 10.4²

169 = 169

Yes

and h = 6 hours, substitute and find the total cost

y = 10 + 2.50(6)

= 10 + 15
