Answer:
Step-by-step explanation:
Semicircle:
diameter = length of the rectangle = 25 cm
Half circumference = πd/2
= 3.14 * 25/2 = 39.25 cm
Perimeter of the figure = 39.25 + 20 + 25 + 20
= 104.25 cm
This question is incomplete. There isn’t enough data to display an answer
Sin 30=opposite side/hypotenuse =8/x
1/2=8/x so 1•x=2•8; x=16
Sin60= opposite side/hypotenuse=y/16
(Sqrt 3)/2=y/16 so 2•y=16• sqrt 3; y=13.856
47-(-38)
47+38
85
hope this helps!
