Answer 1

Answer:

Given:A=x,B=3x,C=y

∴Sum of△le=x+3x+y

180=4x+y

⟹180−4x=y

Also,3y−5x=30

∘m

Subtituting y value, ∴3(180−4x)−5x=30

∴x=30,bysolving

∴y=180−4×30=60

∴A=30

;B=90

;C=60

Hope it helps you keep smiling :)

Answer 2

Answer:

Remember this! (K_{1}(\Delta))/(K_{2} / K) = c/(sigma ^ 2) * (log R ^ 2)/(K_{2} / K) Ratio of areas of two triangles is equal to the ratio of the products of theirbases and corresponding heights.• Areas of triangles with equal heights are proportional to theircorresponding bases.Areas of triangles with equal bases are proportional to theircorresponding heights.
