Answer:
49°
Step-by-step explanation:
arc AB subtends a central angle of 98°
Let <em>O</em> be the center of the circle.
∠OAB = ∠OBA = (180°-98°)/2 = 41°
Assuming that BC is tangent to the circle, ∠OBC = 90°
∠ABC = ∠OBC - ∠OBA = 90° - 41° = 49°
It’s B - F(x) = | x-7 | -3
M+p=475
m=p-61
replace m in equation 1 with p-61: p-61+p=475
2p=475+61=536
p=268
m=207
Answer: perimeter= 2m+22 units
Step-by-step explanation:
length= 2m+1
width= 10-m
p=2(l+b)= 2(2m+1+10-m)
p=2(m+11)
p=2m+22 units
