2 3/4 - 1 = 1 3/4 or 1.75
The answers are:
A= 40°
B= 140°
C=180°
First change it into exponential form that apply any derivation rules needed
Radius = 9m
Diameter = 18 m
Area = 254.34 squared m
Circumference = 56.52 m
I’m guessing is asking for the circumference because it says around
Answer:
1. Find < ACB
2. Use that triangles =180 to find <B = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41
