WebStep 2: Determine the ratio. Since two angles are equal, the triangle is an isosceles right angle triangle and hence two sides will be equal. Therefore let sides a = k, b = k. Thus we have, by the converse of Pythagoras theorem. c = a 2 + b 2 = k 2 + k 2 = 2 k 2 c = 2 k. The ratio of a: b: c is 1 k: 1 k: 2 k o r 1: 1: 2. うどんエキスポ 湯沢市Web6、如图电路,已知r1=3,r2=6,则等效电阻r=( )。 7、电阻上的电流与它两端的电压之是常数,这种电阻称为( )电阻。 8、已知 R1>R2,在它们的串联电路中R1比R2取得的功率( ),在它们的并联电路中R1比R2取得的功率( )。 palazzo pegasoWebJan 28, 2024 · In ΔABC Δ A B C if r1 = 2r2 = 3r3 r 1 = 2 r 2 = 3 r 3 and D D is the mid point of BC B C then cos∠ADC = cos ∠ A D C = A. 7 25 7 25 B. − 7 25 - 7 25 C. 24 25 24 25 D. − 24 … palazzo pegaso firenzeWebCalculate the equivalent resistance Reqof the network shown in Figure 1below if R1= 2R2= 3R3= 4R4, etc and R11= 3 Figure 12.In the Figure 2 below, only the voltage vx is of interest.
