On solving these special right triangle problems? ?

look at picture

Figure 4 ⇒ x = = 5.774

                   y = = 2.887

Figure 5 ⇒ x = 7

                   y = = 4.041

Step-by-step explanation:

Figure 4:

∵ The Δ is right triangle

∴ Use trigonometry function

∵ 5/x = sin(60°)

∴ x = 5/sin(60°) = = 5.774

∵ 5/y = tan(60°)

∴ y = 5/tan(60°) = = 2.887

Figure 5:

∵ The Δ is right triangle

∴ Use trigonometry function

∵ = sin(60°)

∴ x = ×sin(60°) = 7

∵ = cox(60°)

∴ y = ×cos(60°)= = 4.041

A 30°- 60°- 90° triangle has corresponding sides of:  b - b√3 - 2b

The sides are OPPOSITE of the angle (the side the angle is not touching)
