Answer:
807
Step-by-step explanation:
3×19×14+18/2
57×14+18/2
798+14/2
798+9
807
Find two numbers with a sum of 20 and a difference of 14
Make two equations
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are
3 and 17
Answer:
There is a answer to the question
To find the length of arc BC, we use the following formula.
<BDC=1/2 Arc BC
Measure of inscribed angle = 1/2 of measure of the intercepted arc.
Angle BDC= 65°
65=1/2 Arc BC
Arc BC= 2 x 65
Arc BC= 130°
Answer: Measure of Arc BC= 130°
