Use right triangle trig to solve for the missing angles. Round all answers to the nearest tenth (one decimal place).

x=??

Answer 1

we have

sin 30 =perpendicular/hypotenuse

1/2=x/19

doing crisscrossed multiplication

19/2=x

x=9.5

Answer 2

Use sine for this:

• sin 30° = x/19
• x = 19 sin 30°
• x = 19(1/2)
• x = 9.5
