ss below math help major

imyoursgirlsgirl:

Angle:

imyoursgirlsgirl:

everyone keeps sending me that photo but it just confusing

Angle:

the little angle in the pointy corner is half of 100

Angle:

what is the measure of that angle?

imyoursgirlsgirl:

50?

Angle:

good If I plug in angle=50 and small arc = 40 and big arc = x into the equation in the picture I shared: 50 = 0.5(x - 40) do you know how to solve for x?

imyoursgirlsgirl:

no

Angle:

I made a typo 55 = 0.5(x - 40)

Angle:

but also... have you heard of something called the "distributive property" before?

imyoursgirlsgirl:

yes

imyoursgirlsgirl:

ive heard of it but doesnt mean i know it

Angle:

distributive property means that you multiply every that is inside of the parentheses by the one number that is outside of it for example: 2(x+3) = 2x + 6 try doing the same with: 0.5 ( x - 40 ) what do you think you would get?

imyoursgirlsgirl:

ok so i time 0.5 with 40

Angle:

yes, what do you get?

imyoursgirlsgirl:

20?

Angle:

awesome this means that our equation is now: 55 = 0.5x - 20

imyoursgirlsgirl:

ok

Angle:

You can solve this question by trying to think of it as: "What number times a half is equal to 75?"

imyoursgirlsgirl:

37.5?

Angle:

no

imyoursgirlsgirl:

imyoursgirlsgirl:

im confused

Angle:

"What number times (1/2) is equal to 75?"

imyoursgirlsgirl:

i honestly dont know

Angle:

Then I recommend that you fail your class and retake - you're too far behind for me to drag you through a geometry problem like this

imyoursgirlsgirl:

or you could tell me how to find out instead of the answer

Angle:

Step 1. The angle seen in your picture is half of 110 because of the Inscribed Angle Property of Circles Step 2. An Angle Formed Outside of Circle by Intersection of Two Secants is equal to (1/2) times the difference between the two arc lengths. This is why I set up x - 40 in the equation I asked you to solve. Step 3. Use basic algebra to solve the equation 55 = 0.5(x - 40) and get your answer

thx.
