C.
l b +8 l = 6 (divided both side by 5)
set b + 8 = 6 or b + 8 = -6 (because this is an absolute value)
you get answer choice c<span />
The tangent at A is perpendicular to OA, so has a slope that is the negative reciprocal of that of the radius: -1/2.5 = -2/5.
Answer:
m∠1=80°
m∠2=112°
m∠3=131°
m∠4=80°
m∠5=37°
Step-by-step explanation:
First you have to find m∠2
To do that find m∠6 (I created this angle shown in pic below)
Find m∠6 by using the sum of all ∠'s in a Δ theorem
m∠6=180°-(63°+49°)
m∠6=68°
Now you can find m∠2 with the supplementary ∠'s theorem
m∠2=180°-68°
m∠2=112°
Then you find m∠5 using the sum of all ∠'s in a Δ theorem
m∠5=180°-(112°+31°)
m∠5=37°
Now you can find m∠1
m∠1=180°-(63°+37°)
m∠1=180°-100°=80°
m∠4 can easily be found too now:
m∠4=180°-(63°+37°)
m∠4=80°
m∠3=180°-49°
m∠3=131°
Answer: A. 
.
Step-by-step explanation:
- A difference of squares problem is factored as :
- For this both terms in the form of squares and a minus sign between them.
From all the options only option A has both terms square and they minus sign between them.
Also, 
Here a= 3x and b= 4
Hence, the correct answer is A. .
I think it’s 3
i multiplied .2222 times 18
