WebThe correct option is A True Let a,b,c be the length of the sides of the triangle, s be the semi perimeter and Δ be the area. r1 = Δ (s−a) = 24 (12−a) r2 = Δ (s−b) = Δ (12−b) r3 = Δ s−c = 24 (12−c) Since r1,r2,r3 are in H.P. ⇒ 1 r1, 1 r2, 1 r3 are in A.P. ⇒ 2 r1 = 1 r1+ 1 r3 or 2× 12−b 24 = 12−a 24 + 12−c 24 Or a+c= 2b ..... (1) WebMesh current i3 has to be equal to -I because it is the only current flowing through the current source. When you look at R4, however, the resistor current is the combination of (superposition of) two mesh currents, i3 and i2. You nearly got the expression for the voltage across R4 correct. It equals R4 (i2 - i3). hierarchy exemption https://drogueriaelexito.com
