Answer:
base: 2/3 ft (Answer C)
Step-by-step explanation:
Recall that the formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
Here A = 2/5 ft^2 = (1/2)(b)(6/5 ft)
We must solve this for b. Start by multiplying all terms by 10 to eliminate the fractions:
10(2/5 ft^2) = (6 ft)(b), or
4 ft^2 = (6 ft)b, or
4 ft^2
b = ---------------- = 2/3 ft (Answer C)
6 ft

Step-by-step explanation:
Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13
For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.

Answer:
(a) exactly two unique triangles
Step-by-step explanation:
The third angle is ...
180° -50° -80° = 50°
Two of the angles are the same, so two of the sides are the same length. The given side measure can be either one of the two unique side lengths, giving rise to exactly two unique triangles.
