The correct answer is

1. 18yd 2ft 4inch

2. 23.5 cm

3.53.5 cm



Explain


1. Use the 1 yard =36 inch

1 foot = 12 inches

So divide 676/36 =18yrd


And divide 28/12= 2

And remaining is 4


2. the formula is

Sin= opposite side / hypotenuse


Cos 36 = pr / 11.8

11.8 cos 30 ^0 =pr

9.55cm = pr

And the rest step is in the picture






3. Cos 43 = ac/ab = 16.2/ab

Ab= 16.2/cos 43

Ta 43= bc/ac= bc/16.2


Perimeter = 16.2/cos43 +16.2 +16.2 tan 43

= 53.5 cm



Hopefully this help you :)
