Anwer is B...... . ........
Answer:
Step-by-step explanation:
<u>Use formula:</u>
- A = 1/2 Pa, where P-perimeter of the polygon, a- apothem
1)
- A = 1/2(7*13.9)(14.4) = 700.56 ≈ 700.6
Correct choice is B
2)
Correct choice is A
Sounds as tho' you have an isosceles triangle (a triangle with 2 equal sides). If this triangle is also a right triangle (with one 90-degree angle), then the side lengths MUST satisfy the Pythagorean Theorem.
Let's see whether they do.
8^2 + 8^2 = 11^2 ???
64 + 64 = 121? NO. This is not a right triangle.
If you really do have 2 sides that are both of length 8, and you really do have a right triangle, then:
8^2 + 8^2 = d^2, where d=hypotenuse. Then 64+64 = d^2, and
d = sqrt(128) = sqrt(8*16) = 4sqrt(8) = 4*2*sqrt(2) = 8sqrt(2) = 11.3.
11 is close to 11.3, but still, this triangle cannot really have 2 sides of length 8 and one side of length 11.
Answer:
She will use 13 quarter cups of oatmeal
Step-by-step explanation:
3 1/4 = 13/4
x/4 = 13/4
4(x/4) = 4(13/4)
x = 13
Answer:
3 lines of symmetry
Step-by-step explanation:
the lines go through the vertices of the triangle
