Question

Solve for xx. Round your answer to the nearest tenth if necessary. Figures are not necessarily drawn to scale.

first Tri has 19 and 16 but no 3rd number
second tri has 54 and x no 3rd number

Answer 1

If the two triangles are similar and the given sides correspond (19 ↔ 54 and 16 ↔ x), then

x/54 = 16/19 => x = 54*(16/19) = 864/19 ≈ 45.4737.

Rounded to the nearest tenth: x = 45.5.

(If the triangles aren’t similar or the correspondence is different, more information is needed.)
