Answer: y = 5
Step-by-step explanation:
This triangle is isosceles.
So, ∠ABC = ∠ACB = 75°
Now,
sum of interior angles of a triangle = 180°
∠ABC + ∠ACB + ∠BAC = 180°
75° + 75° + (4y + 10)° = 180°
160° + 4y° = 180°
4y° = 20°
y = 5
$6.25 is the price it will cost for 15 sq ft
Answer:
interest = 250
time = 3 years
rate = 2%
we know
P = I*100/(R*T)
= 250*100/6
=4166.67
