Answer 1

Answer:

Thanks ;)

Step-by-step explanation:

• A number is divided into two parts so that the difference of the parts is 40. If four-fifth of the smaller part exceeds one-third of the greater part by 24. Find the number

Answer 2

$\sin(θ) = \frac{11}{52}$

We know that ,

sin²θ + cos²θ = 1

$( \frac{11}{52} )^{2} + \cos^{2} (θ) = 1$

${ \cos}^{2} θ = 1 - \frac{121}{2704}$

$\cos^{2}θ = \frac{2704 - 121}{2704}$

$\cos^{2}θ = \frac{2583}{2704}$

$\cosθ = \sqrt{ \frac{2583}{2704} }$
