In the diagram shown the following is known: Given: AB bisect ZCBD and BD = BC.
Prove: AADB = AACB using rigid motion reasoning
А.

(a) Explain why we know that mZCBA = m_DBA but we
don't know that mZCAB = MZDAB. Mark the known
equal angles.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

mx+89b(-98)nb

step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
