Answer:
15°
Step-by-step explanation:
∠ABC and ∠DBC form a straight angle and are supplementary, thus
∠ABC + 30 = 180 ( subtract 30 from both sides )
∠ABC = 150°
Since AB = BC then ΔABC is isosceles with ∠BAC = ∠BCA
The sum of the 3 angles in the triangle = 180°
Hence ∠BAC = 
= 
= 15
That is ∠a = 15°
Answer:
5%
Step-by-step explanation:
150,000/100=1500 7500/1500=5
The entire shape is 50cm squared. Multiply that by twelve, you get 600. Hope that’s right, and it helps!

Answer:
y = 0.0765x
Step-by-step explanation:
We have that:
y is the total taxes paid.
x is the total wages earned.
The total taxes paid is a function of the total wages earned.
For wages less than the maximum taxable wage base, Social Security contributions (including those for Medicare) by employees are 7.65% of the employee's wages.
So 7.65% of the total wages earned are paid in taxes. We write the percentage as a decimal, so 7.65/100 = 0.0765
So the answer for a) is:
y = 0.0765x
