Answer: 80°
Step-by-Step Explanation:
By Angle Sum Property of a Triangle, all angles in a Triangle add up to 180°
Finding the Value of ‘x’ :-
2x + 3x + 4x = 180
5x + 4x = 180
9x = 180
x = 180/9
=> x = 20
Finding each Angle :-
2x = 2(20) = 2 * 20 = 40°
3x = 3(20) = 3 * 20 = 60°
4x = 4(20) = 4 * 20 = 80°
Hence, the Largest Angle is 80°

Answer:
Interest = $47.34
Step-by-step explanation:
Formula:-
Simple interest I = PNR/100
P - Principle amount  
N - number of years
R - Rate of interest
It is given that
P = $ 1600
R = 6%
Number of days = 180 days
<u>To find the simple interest for 1 year(365 days)
</u>
 I = PNR/100
 = (1600 * 1 * 6)/100 = $96
<u>To find the interest for 180 days
</u>
For 365 day I = $96
For 180 days I = (180/365) * 96
I  = $47.34
