Answer:
The answer to your question is ∠3 = 24°
Step-by-step explanation:
Data
∠4 = 11x
∠3 = 4x
Process
1.- From the picture, we know that angles 3 and 4 are complementary so if we sum them up the result is 90°.
∠3 + ∠4 = 90°
2.- Substitution
4x + 11x = 90°
3.- Simplification and result
15x = 90°
x = 90/15
x = 6
4.- Find angle 3
∠3 = 4(6)
∠3 = 24°
your answer would be x=4 i believe
Answer:
- $450,000 at 10%
- $50,000 at 9%
Step-by-step explanation:
Let x represent the amount invested at 10%. Then the total interest earned per year is ...
0.10x + 0.09(500,000-x) = 49,500
0.01x = 49500 -45000
x = 4500/0.01 = 450,000
$450,000 was deposited in the 10% account; $50,000 was deposited in the 9% account.
90.95 rounded to the nearest whole # is 91
