What is the length of JM in the given figure?
umka21 [38]

Answer:  B. 30

<u>Step-by-step explanation:</u>

When given a secant and a tangent, the formula is:

exterior of secant × secant = tangent²

                     KM   ×    JK     =    LK²

                      10   ×  (JM + 10) = 20²

                            10JM + 100 = 400

                                     10JM = 300

                                         JM =  30

Im not sure how to find the surface area. 35 points
Serga [27]

Answer: 3060 ft^2

Step-by-step explanation:

We will calculate the surface area of the rectangular prism and the triangular prism separately and then subtract off the face that isn't on the surface.

For the rectangular prism:

SA= Ph + 2B

P = 36+36+10+10

P = 92

B = 36*10 = 360

SA = 92*20+2*360

SA = 1840+720

SA = 2560

We subtract off the face on the right of the rectangular prism because it isn't on the surface so we get 2560-200 = 2360

Now for the triangular prism:

SA= Ph + 2B

P = 15+20+25

P = 60

B = 15*20/2

B = 150

SA = 60*10+2*150

SA = 600+300

SA = 900

Again we subtract off the face on the left bescause it's not on the surface so we get 900-200 = 700

Therefore, the total surface area = 2360+700 = 3060 ft^2
