Find the angle z in the following triangle.
< RIght angled triangle with sides of length 8mm, 5mm and h. Unknown angle z denoted.Use SOH CAH TOA in trigonometry to label the triangle accordingly, then find that 'tan' is to be used. Finally, use the inverse of tan to isolate the angle z and find its numerical value.tan(z) = o/a = 5/8Therefore, z=tan-1(5/8) = 32.01
