Question

If cos x =5/13 and x is an acute find the value of tan x

Answer 1

Step-by-step explanation:

if cosx = 5/13

then make right angle triangle whose hypotenuse length is 13. and one base length is 5. so another 3rd side length

= underroot of 169-25

= underroot of 144

= 12

so we can say tanx = 12/5
