Answer:

31

Step-by-step explanation:

In circle S: XB and XD are tangents at B and D

then SB perpendicular to AX and SD perpendicular to XC

In triangle SDX:  SD = 12 and SX =20 by using Pythagoras Theorem

XD=\sqrt{20^{2} -12^{2} }=16

XD = XB  tangents to circle S from point X

XA = XC tangents to circle R from point X

then BA = DC = 15

then XC = XD + DC = 16 + 15 = 31

How do I find the area of each shape
Ad libitum [116K]

Answer: the formula is (A=bh1/2)


Step-by-step explanation: #4 (The triangle)

First let’s find the base length of the triangle.

28 - 16 = 12

Ok now let’s do the real math now

Area  = bh1/2

Area = (12)(16)(1/2)

Area = 96
