Answer:
the 2nd and 5th one
Step-by-step explanation:
14 < n-3
add 3 to each side
14+3=17
-3+3 cancels out
we're left with 17<n
thus meaning the second and fifth one are correct
Answer:
21 degrees
Step-by-step explanation:
To find this, we are going to use the appropriate trigonometric ratio
The right angle faces the length 22 which is the hypotenuse
The marked angle faces the length 8 which makes it the opposite
The trigonometric ratio that links the two is the sine
The sine is the ratio of the opposite to the hypotenuse
So, we have it that;
sine ? = 8/22
? = arc sine 8/22
? = 21 degrees
