Answer:
Since there are two angles which are equal in the triangle we can make our equation as-
2x+60=180
(180 cuz the sum of all angles in a triangle will ALWAYS be 180)
so if we solve,
2x=120
x=120/2
x=60
thus x=60
There was $800 deposited at 9% interest and $400 deposited at 4% interest.
The formula for simple interest is I = prt. Using our information we have:
88 = x(0.09)(1) + (1200-x)(0.04)(1)
88 = 0.09x + 48 - 0.04x
88 = 0.05x + 48
Subtract 48 from both sides:
88 - 48 = 0.05x + 48 - 48
40 = 0.05x
Divide both sides by 0.05:
40/0.05 = 0.05x/0.05
x = 800
1200 - x = 400
