Answer: 32 Cm squared
Step-by-step explanation:
The area of a triangle is (1/2) base times height.
(1/2) x (8) x (8) = 32
Step-by-step explanation:

X=74°
Explanation: the sum of the interior angles equal 180°. We are given an isosceles triangle, which has 2 equal sides and one that isn’t. We can see that the bottom two angles are the same.
Take 180 and subtract 32. We have 148. We have two angles that we know are the same. Divide that by 2. That’s 74.
We can check that to make sure it equals 180°
32+74+74=180.
Therefore, it’s correct.
If the population of the animals decreases by about 21% of its current population, it means that the population next year is only 1 - 0.21 or 0.79 of its current population. Thus, the multiplier for the rate of the exponential decay is 0.79.
