**Answer:**

je suis super nul en math desolee

A.because -18 changes into positive and that would make it 18 + 12=30 and you divided it by -3x which should have x equal to -10

**Answer:**

a) XY , XVY

b) 248°

c) UV , UY

d) 6√5 = 13.42

**Step-by-step explanation:**

a) The minor arc is **XY**

The major arc is **XVY**

b) ∵ The measure of the minor arc is 112°

∵ The measure of the circle is 360°

∴ The measure of the rest arc = 360 - 112 = **248°**

c) **UV** is the tangent to the circle

**UY** is the secant to the circle

d) ∵ UV is a tangent to the circle at V

∵ UY is a secant to the circle

∴ (UV)² = (UX) × (UY)

∵ UX = 9 and XY = 11 ⇒ ∴ UY = 11 + 9 = 20

∴ (UV)² = 9 × 20 = 180

∴ UV = √180 = **6√5** = **13.42**

I'm probably wrong but since 1/2 = 50/100 and 1/3 = 33.333 repeating. Wouldn't it be 83/100 are either teal or red?
