Sample: the first question, solved
Explain why trigonometry is useful for "indirect measurement."
📘 Worked solution
✓It allows calculating unknown heights or distances using measurable angles and distances, without needing to physically measure the inaccessible object.
And one from the hard end
"A cliff's height is estimated two ways: (1) trigonometry - 80m away, 37° angle of elevation; (2) similar triangles - the cliff casts an 80m shadow while a 1.5m stick casts a 2.0m shadow. Calculate both and compare."
