Answer:

634

Step-by-step explanation:

The population of the birds in 2001 = 230000

From 2001 to 2021 = 20 years

Given:

y = 200000(0.75)^{x}

where x is the number of years since 2001.

The population of the birds after 20 can be determined by;

y = 200000(0.75)^{20}

  = 200000(3.171211939 x 10^{-3})

  = 634.2424

y = 634

Thus, there would be 634 endangered birds in 2021.

Find the measure of the missing angles.
Karolina [17]

Answer:

angles b and c should be 153° each.

Step-by-step explanation:

We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°
