ANSWER THIS QUESTION for a nice surprise...

Answer 1

Answer:

Step-by-step exp

sin 40° =

x

8

or

x = 8 × sin 40°

= 5.142300877 cm

= 5.1 cm to 1 decimal place

Answer 2

Answer:

B) 26.565

Step-by-step explanation:

For angle θ :-

• => perpendicular is 3.1
• => base is 6.2

tan θ = perpendicular/ base

= 3.1/ 6.2

= 1/ 2

= 0.5

tan θ = 0.5, for angle θ = 26.565 (using trigonometry table)

so the value of θ is 26.565
