The sum of angle in the triangle = 180 °
so c = 180-(90+37)
c= 180-127
c= 53°
It’s 85.645
just make 87.3 into 87.300 to make both number have the same amount of decimal places and just subtract normally after.
The circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r".
Therefore the radius is √49=7 and the center coordinates are (0,0)
