Find the values of x and y<br> - PLEASEEE HELP
Elden [556K]

Answer:

x= 34°

y=5

Because segments AB and BC are congruent, their corresponding angles (<BAD and <BCD) would also be congruent to each other, meaning that both would be 56°.

Knowing that triangles add up to 180°, the whole triangle (ABC) would then have 2 angles that are 56° and the top angle (<ABC) would be 68°

Splitting those in half ( because <ABD and <CBD are congruent), each would be 34° (thus x=34°)

Looking now at the two separate triangles (ABD and CBD), we can determine that both <BDA and <BDC are 90° (right angles) because 180-34-56=90°.

Therefore, since both triangles have all congruent angles, both triangles are the same! So, since segment AD=5, segment CD would also be 5 (y=5).

If your starting salary is $35,000 and you receive a 6% increase at the end of every year, what is the total amount, in dollars,
aksik [14]

The starting salary is $35,000.

Salary is increased by 6% at the end of every year.

Nos of years worked = 16 years

Total salary earned in 16 years is given by An * (( 1+i )^n - 1 ) / i

Where, An = Present Salary = $35000

i = Increase in salary per year = 6% = 0.06

n = number of years = 16

= 35000 * ( 1.06 ^16 - 1 ) / .06

= 35000 * ( 2.54035 - 1 ) / .06

= 35000 * 1.54035 / .06

= 898538

Total earnings in 16 years is $ 898538

Which choice shows (3+9) + 13 correctly rewritten using the associative property and then correctly simplified?
il63 [147K]

Answer:

Step-by-step explanation:

(3+9) + 13 could also be written as:

3 + 9 + 13 = 25, or

3 + (9 + 13) = 3 + 22 = 25, or

(3 + 9) + 13 = 12 + 13

We can group the addends in any way desired; this illustates the associative property.
