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°


In circle o, and are diameters. the measure of arc ab is 55° and the measure of arc cd is 25°. circl

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

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.
