Cd is perpendicular bisector of both xy and st and cy=20 find ct a) 7 b) 9 c) 15 d) 14

Option C) 15

Step-by-step explanation:

It is given that CD is perpendicular bisector of both XY and ST and CY = 20

We have to find the measure of CT.

In the triangles CSM and CTM

SM = MT = 7 (CD is perpendicular bisector of ST)

∠ CMS = ∠ CMT = 90°

Side CM is common in both the triangles.

So, Δ CSM ≅ Δ CTM

Therefore, side CS = side CT = 15

Option C) 15 is the correct option.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
