Question

cos theta =5/13
Find the value of tan theta
​

Answer 1

Step-by-step explanation:

sin^2@=1-cos^2@=1-(5/13)^2. sin@=12/13. tan@=sin@/cos@ tan@=12/5

Answer 2

Answer:

12/5

Step-by-step explanation:

cos theta = adjacent side / hypotenuese = 5/13

so the sides are 5,13,X

By Pythagoras theorem

opposite^2 + adjacent^2 = hypotenuese^2

x^2 + 5^2 = 13^ 2

x^2+ 25 = 169

= 169 - 25

x^2 = 144

x = √144

x = 12 cm

tan theta is opposite side / adjacent side

that is 12/5
