(x - y + z) : (y - z + 2w) : (2x + z - 10) = 2:3:5 Then ( 3x + 3z - 2w) : w = ?pgvzcmckyc?

Step-by-step explanation:

in question given ,x = 2, y = 3, z = 5 in this way

(3x+3z+2w) and find the value of w . according to given values and put

Hi

Step-by-step explanation:

In similar triangles ∠A=∠A', ∠B=∠B', ∠C=∠C'.

∠A=∠A', 4x-4=51-x,  5x = 55, x=11
∠A=∠A', 4*11-4=51-11, 40=40, ∠A=∠A'= 40⁰

∠B=∠B', 6x - 1 = 4x + 21, 6*11 -1 = 4*11 + 21, 65 = 65, ∠B=∠B'=65
∠C=∠C', 8x - 13 = 6x + 9, 8*11 -13 = 6*11 +9, 75 = 75, ∠C=∠C' = 75

 ∠B=∠B'=65, ∠C=∠C' = 75
So, answer is D.
