Answer:
Step-by-step explanation:
Use the Pythagorean theorem to find the altitude.
h^2 = 9^2 - 6.4^2
h^2 = 40.04
h = 6.328
area = base * height/2
area = (2 * 6.4) * 6.328/2
area = 40.5 square units
Answer:
true
Step-by-step explanation:
The answer is 65 if you add on by three
L = 10 mw = 11 mh = 5 md = 15.6844 mS = 430 m²V = 550 m³ x 2 = 1100m³
Agenda:l = lengthw = widthh = heightd = diagonalS = surface area V = volume
Answer:
c=28
Step-by-step explanation:
In a convex polygon, all the exterior angles are congruent to each other.
I'll be choosing the two angle degrees of 4c-28 and 3c and set them equal to each other.
4c-28=3c
Therefore, c=28
