Question

if tan theta is equals to 3 by 4 then find cos theta + sin theta value​

Answer 1

Answer:

Step-by-step explanation:

tan theta=3/4

b/p=3/4 (tan theta = theta की सम्मुख भुजा/संलग्न भुजा)

b/p=3/4=k

b=3k, p=4k

h=√b^2+p^2

h=√{(3k) ^2+(4k) ^2}

h=√(9k^2+16k^2)

h=√25k^2

h=5k

sin theta =b/h=3k/5k=3/5

cos theta=p/h=4k/5k=4/5

cos theta+sin theta=4/5+3/5=7/5 ans..
