Answer:
Radius = 14 units
Center = ( 6, 8)
Step-by-step explanation:
The correct equation is ,
=> (x-6)² + (y-8)² = 196
=> (x-6)² + (y-8)² = 14²
- Compare to Standard form , which is ,
=> ( x - h)² + ( y - k)² = r²
- ( h , k ) is Center
- r is radius
Hence on comparing we have,
- Radius = 14 units
- Center = ( 6, 8)
Answer:
421/6 degrees
Step-by-step explanation:
The acute angles of a right triangle are complementary, so
![10x+6+2x+7=90 \\ \\ 12x+13=90 \\ \\ 12x=77 \\ \\ x=\frac{77}{12}](https://tex.z-dn.net/?f=10x%2B6%2B2x%2B7%3D90%20%5C%5C%20%5C%5C%2012x%2B13%3D90%20%5C%5C%20%5C%5C%2012x%3D77%20%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B77%7D%7B12%7D)
So, the acute angles measures 421/6 degrees and 119/6 degrees, and thus the larger angle is 421/6 degrees.
