Answer:
c=38
Step-by-step explanation:
It’s 20 degrees because all triangles are all equal up to 180° and so if you add 135° to 25° you get 160° and so minus 160 from 180 and you’ll get 20°
Simple interest rate for one year = 1.5%
simple interest rate over 5 years = 1.5 x 5 = 7.5%
100% + 7.5% = 107.5%
107.5% = $19500
1% = 181.3953
100% = $18140.50
He needs to put in $18140.50 so that he can get $19,500 at the end of 5 years.
X+ 77.5 because if you subtract 25 from 180 you get 155. Then divide 155 by 2 and you get 77.5
