a triangular flower bed needs a thin metal border all the way around it. The sides are 7 feet, 6 feet, and 9 feet long.

Excuse my awful triangle drawing skills, haha..
So essentially you need to find the perimeter which is done by adding the lengths of the sides.. this gives you 22ft.
Then for part b you need to convert 22ft to yards which gives you 7.3 yards.
Since you can only buy a whole number of yards, you'll actually need 8 yards.
So if the boarder is $8.75 per yard, and you need 8 yards, how much would it cost?
Hope this was helpful.

Step-by-step explanation:
Given that is a right angled triangle.
and
Kindly refer to the attached image of in which all the given angles are shown.
To find:
sin(38°) = ?
a) cos(38°)
b) cos(52°)
c) tan(38°)
d) tan(52°)
Solution:
Let us use the trigonometric identities in the given .
We have to find the value of sin(38°).
We know that sine trigonometric identity is given as:
....... (1)
Now, let us find out the values of trigonometric functions given in options one by one:
....... (2)
By (1) and (2):
sin(38°) cos(38°).
...... (3)
Comparing equations (1) and (3):
we get the both are same.
