Answer:
220 degree
Step-by-step explanation:
Given the radius=18cm , pi=3.14.. , area=198π
Area of a sector =∅×π×r²/360
or,198π=Θ×π×r²/360
or,Θ=360×198π/πr²
∴Θ=220°
Answer:
m<B: 56
Step-by-step explanation:
All triangles add up to 180
<B = x
x + 34 + 90 = 180
x + 124 = 180
x = 56
161 - 49 = 128
128 / 2 = 64
64 + 64 +49 =161
first number is 64
second is 113
