2/5 = 2/10 + k
multiply both sides (each term) by 10, we get
10×2/5 = 10× 2/10 + k ×10
4 = 2 + 10k
OR 10k = 4 - 2
10 k = 2
k = 2 / 10
Or k = 1/5

Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° =
, sin30° =
, then
cos30° =
=
=
( cross- multiply )
2x = 20
×
= 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° =
=
=
( cross- multiply )
2y = 20
( divide both sides by 2 )
y = 10
