Question

If cos theta=0.6 find the value of 5 sin theta - 6 tan square theta

Answer 1

Answer:

-20/3

Step-by-step explanation:

cos = 0.6 = 6/10 = 3/5

cos = b/h = 3x/5x

p = √ (h)^2 - ( b) ^2

p = √ (5x)^2 -(3x) ^2

p = √ 25x^2 - 9x^2

p = √ 16x^2

p = 4x

sin = p/ h = 4x/5x = 4/5

tan = p/b = 4x/3x= 4/3

5*sin -6 tan ^2 = 5* (4/5) -6( 4/3)^2 =

4-6*16/9 = 4-32/3 = 12-32/3 = -20/3
