Answer:
b=√3
a=2
Step-by-step explanation:
Since you are given one side and an angle, you can immediately think of using cos, sin, and tan
When solving for b, you would set up your equation with tan30=1/b since tangent is opposite/adjacent
Next for a, you would solve for sin30=1/a since sine is opposite/hypotenuse
Hope this helps! :)

J = mid of GH.
So:
Perimeter IJH is then calculated as:
Answer:
The original price of the sweater was $28
Step-by-step explanation:
To find out the answer to this problem you need to first convert the percent into a decimal which would be 0.4 and then to solve the problem in one step you need it to be 140% which would be 1.4 as a decimal. Then you need to multiply 20 by 1.4 which gives you 28 and 28 would be the total cost of the shirt at it's regular price.
