m arc EAC=280°
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of arc BC
we know that
m arc EAC=m arc EAB+m arc BC ----> equation A
we have
m arc EAB=180° ----> because the line segment BE is a diameter
m arc AB+m arc BC+m arc CD=180° ----> because the line segment AB is a diameter
substitute the given values and solve for m arc BC
55°+m arc BC+25°=180°
80°+m arc BC=180°
m arc BC=180°-80°=100°
step 2
Find the measure of arc EAC
m arc EAC=m arc EAB+m arc BC ----> equation A
we have
m arc EAB=180°
m arc BC=100°
substitute
m arc EAC=180°+100°=280°

SI=(P*R*T)/100
P=2000
R=1.5
T=6
SI=(2000*1.5*6)/100
=(2000*9)/100
=180
Neil will earn interest of 180
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53

The solution is given in the image below
Here,
tip=18%of $32
tip=(18/100)*32
=0.18*32
=$5.76
Total payment=32+5.76=$37.76
The wood before starting =12 feet
Left wood=6 feet
Wood used till now=12-6=6 feet
Picture frame built till now= 6/(3/4)
=8 pieces
Therefore, till now 8 pieces have been made.
