The figure shows two triangles, where I represents the length of the common side AB. (Figure is not drawn to scale.)

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

you got this ; }
