Answer:
Correct option: first one -> 45°
Step-by-step explanation:
FC is a diameter, so the arc FBC measures 180°.
If we have that FBC = FB + BC, then we can find the value of BC:
FB + BC = 180
135 + BC = 180
BC = 45°
If we call the center of the circle 'O, we have that the central angle EOF and the central angle BOC are vertically opposite angles, so EOF = BOC.
The central angles have the same measure that the arcs they are related, so we have that:
angle BOC = arc BC = 45°
angle BOC = angle EOF
angle EOF = arc EF = 45°
Correct option: first one

Answer:
Infinite. Please Mark Brainliest, this took a lot of effort.
Step-by-step explanation:
After going through the process of solving, you get 0=0, meaning true for all z
-2z+2+4z=16/5+2z-6/5
Group Like Terms
-2z+4z+2=16/5+2z-6/5
Add similar terms
2z+2=16/5+2z-6/5
Group Like Terms
2z+2=2z-6/5+16/5
<em>Combine the Fractions</em>
Apply the rule a/c plus or minus b over c equals a plus or minus b over c
=(-6+16)/5
Add/Subtract the numbers
=10/5
Divide the numbers
=2
2z+2=2z+2
Subtract 2 from each side
2z+2-2=2z+2-2
Simplify
2z=2z
Subtract 2z from each side
2z-2z=2z-2z
Simplify
0=0
Both sides are equal, true for all z
Answer:
25
Step-by-step explanation:
Y=mx+b
Y1-Y2/X1-X2
14-10/5-3 = 4/2 = 2
Plug in (3,10):
(10)=2(3)+b
Solve:
10=6+b
B=4
M=2
