Answer:
The perimeter is 55.68 cm.
Step-by-step explanation:
We have 2 sides as 9 cm.
We have the diameter as 12 cm. So, radius = 6 cm
Circumference of complete circle is = So, circumference of half circle will be
Now the perimeter of the whole figure will be given as:
=
=
= 55.68 cm
Therefore, the perimeter is 55.68 cm.

Answer:
sin(x)=1/
Step-by-step explanation:
The trigonometric identities involve trigonometric functions. Here we will be using Trigonometric identity
sin²x = 1 /( 1+cot²x )
now cot(x)= -3
⇒ cot²x= (-3)²
⇒ cot²x= 9
sin²x= 1/( 1+9)
⇒ sin²x = 1/10
taking under root on both the sides we get
√sin²x=/
⇒ sin(x)=± 1/
