Step-by-step explanation:

20) the angle at the base of the right angle triangle is alternate to the given angle. Since alternate angles are equal, it means that the base angle of the right angle triangle is 27 degrees.

To determine x, we would apply

the Sine trigonometric ratio.

Sin θ, = opposite side/hypotenuse. Therefore,

Sin 27 = x/580

x = 580Sin27

x = 580 × 0.454

x = 263.3 to the nearest tenth.

21) the angle at the base of the right angle triangle is alternate to the given angle. Since alternate angles are equal, it means that the base angle of the right angle triangle is 18 degrees.

To determine x, we would apply

the Tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 18 = x/2

x = 2tan18

x = 2 × 0.3249

x = 0.6 to the nearest tenth.
