Question

If 4 tane = 3, evaluate
4 sin 8-cos+1
4 sin + cos-1​

Answer 1

Step-by-step explanation:

4tan = 3 = tan = 3/4

we know, tan = perpendicular/base so, after comparing , perpendicular = 3 and base = 4

hypotenuse = v(3² + 43) = 5 now, sin = perpendicular/hypotenuse 3/5 =

cos = base/hypotenuse = 4/5

now, (4sin - cos + 1)/(4sin + cos - 1) = (4 x 3/5 - 4/5 + 1)/(4 × 3/5 + 4/5 - 1) = (12 - 4 + 5)/(12 + 4 - 5)

Answer 2

Step-by-step explanation:

4tanx=3

tanx=3/4

Pythagoras triplets 3,4,5

perpendicular=3. base=4, hypertenis=5

sinx=3/5

cosx=4/5

4sinx-cosx+1

4×3/5-4/5+1

12/5-4/5+1

8/5+1

4sinx+cosx-1

4×3/5+4/5+-1

12/5+4/5-1
