Answer:

ANSWER: ADC=82

bda = 144

16x+80=144

16x=64

x=4

9(4)+46=82

adc=82

Answer:

82 degrees

Step-by-step explanation:

Angle <em>BDA </em>is 144 degrees.    GIVEN

Since angle <em>BDC </em>is 7x+34 degrees and angle <em>CDA </em>is 9x+46 degrees, we can figure out what x is by adding the two expressions.

7x+34+9x+46=144

First, combine like terms.

16x+80=144.

Then, subtract 80 on both sides.

16x=64

Dividing x on both sides gives us:

x=4

Since the question asked to find angle <em>ADC</em>, we substitute x into 9x+46.

This becomes 36+46=82.

For this case we have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease rate
 t: time
 Substituting values we have:
 y = 200 * (0.946) ^ t
 Answer:
