4) Find the surface area of a square pyramid with a slant height of 15 and a base length of 12. *
Your answer

What is the solution of sqrt x+2-15=-3

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
