Answer:

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

$\frac{RS}{FG}$ = $\frac{ST}{GH}$ ( substitute values )

$\frac{RS}{21}$ = $\frac{4}{12}$ ( cross- multiply )

12 RS = 84 ( divide both sides by 12 )

RS = 7 cm

A triangle has sides with lengths of 3 feet, 6 feet, and 8 feet is it a right triangle?

Zielflug [23.3K]

Answer:

$Solution,\\Longest~side(h) = 8ft.\\Perpendicular(p) = 3ft.\\Base(b) = 6ft.\\Now, \\h^2 = (8)^2 = 64sq.ft.\\p^2+b^2 = 3^2+6^2 = 9+36 = 45sq.ft.\\Since, h^2\neq p^2+b^2, ~the~triangle~is~not~a~right~triangle.$
