Alright so, the angle AHI and J are actually the same. So they're both going to be 63 degrees
Knowing that, now you have to find the 3rd angle
All triangles angles add up to 180
63+45+x=180
108+x=180
-108 -108
72=x
Answer:
be more descriptive plz
Step-by-step explanation:
7/√2 cm
Area of circle = 77 cm^2
=> π(r)^2 = 77
=> (22/7) x (r)^2 = 77
=> (r)^2 = (77 x 7) / 22
=> (r)^2 = 49/2
=> (r) = 7/√2 cm
