Answer:
1,3,9
Step-by-step explanation:
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/
16
––
30
because there are 30 inches in all and 16 out of the 30 are concrete
Answer:
subtract 4 from both sides
The answer would be b because if you substitute 5 in for x y=2x-6 would equal 4 and y=5x-21 would equal 4. I hope this helps!
