The interior angles in any triangle sum to 180 degrees, so the measure of angle E is 180 - 65 - 50 = 65 degrees.
Assuming side d is opposite angle D, side e is opposite angle E, and side f is opposite angle F, we can use the law of sines to determine the side lengths e and f.
Angles E and F have the same measure, so 
as well.
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.
5w + 20
Both terms have 5 in common, so you can factor out 5. Divide everything by 5, then put what you have in parentheses with the 5 outside of the parentheses.
5(w + 4) is your answer.
