Answer:
X=55°
Y=30°
Step-by-step explanation:
2y=x+5
Y=1/2x+2.5
3y+30=4x-100
3(0.5x+2.5)+30=4x-100
1.5x+7.5+30=4x-100
4x-1.5x=137.5
2.5x=137.5
X=55°
Y=30°

Answer:
62.5 interest on 2500 loan
Step-by-step explanation:
Given that,
amount of loan bank has granted = 2500
number of years = 90 days
90 days = 3 month
3 months = 1/4 year = 0.25 year
interest rate = 10%
= 10 / 100
= 0.1
Formula to use
Principal * interest rate expressed as a decimal * time in years
2500 * 0.1 * 0.25
62.5
Hence, the interest on the loan of 2500 with 10% interest rate for 90 days is 62.5
