The short leg is </span>the side opposite the 30 degree angle. If the short leg =x, then the hypotenuse = 2x

The ratio of the short leg to the hypotenuse in the given triangle is cos(60°)

Answer for 23 plz plz plz

Answer:

A₍ₙ₎ = - 74 + (n-1) x 6

Step-by-step explanation:

A₍ₙ₎ = A₍₁₎ + (n-1) x d

A₍₁₈₎ = 28 = A₍₁₎ + 17 x d ..... (1)

A₍₄₀₎ = 160 = A₍₁₎ + 39 x d .....(2)

(2)-(1) 132 = 22d

d = 6

A₍₁₎ = 28 - 17 x 6 = -74

formula: A₍ₙ₎ = - 74 + (n-1) x 6
