Answer:
40.5 cm²
Step-by-step explanation:
sorry I can't explain further. namaster yung pagsolve ng triangles in one look e (di naman sobra). pero I'm sure it's correct.
30—60—90 po kasi yung triangle and in the ratio of its sides, shorter leg is equal to 2hypo. since 18cm ang hypo, means 9cm yung shorter leg. yung shaded region naman is a right triangle. congruent yung dalawang legs nya so it means ang base and height nya is also 9cm.
Area of a ∆ = ½bh
½(9cm)(9cm)
½(81cm²)
40.5cm²
pa brainliest po, thanks
