Question

if sin theta equal
to 4 by 5 find the value of 4 tan theta minus 5 cos theta by sec theta + 4 cot theta​

Answer 1

Step-by-step explanation:

sin theta=p/h=4/5 so we should find b from this equation

b=✓h²-p²

✓5²-4²

✓25-16

✓9=3

4tan theta - 5 cos theta by sec theta + 4 cot theta

4×p/b - 5×b/h divide by h/b + 4×b/p

4×4/3 - 5×3/5 divide by 5/3 + 4×3/4

16/3-3 by 5/3+ 3

7/3 by 14/3

7/14=1/2
