Answer:
The perimeter (to the nearest integer) is 9.
Step-by-step explanation:
The upper half of this figure is a triangle with height 3 and base 6. If we divide this vertically we get two congruent triangles of height 3 and base 3. Using the Pythagorean Theorem we find the length of the diagonal of one of these small triangles: (diagonal)^2 = 3^2 + 3^2, or (diagonal)^2 = 2*3^2.
Therefore the diagonal length is (diagonal) = 3√2, and thus the total length of the uppermost two sides of this figure is 6√2.
The lower half of the figure has the shape of a trapezoid. Its base is 4. Both to the left and to the right of the vertical centerline of this trapezoid is a triangle of base 1 and height 3; we need to find the length of the diagonal of one such triangle. Using the Pythagorean Theorem, we get
(diagonal)^2 = 1^2 + 3^2, or 1 + 9, or 10. Thus, the length of each diagonal is √10, and so two diagonals comes to 2√10.
Then the perimeter consists of the sum 2√10 + 4 + 6√2.
which, when done on a calculator, comes to 9.48. We must round this off to the nearest whole number, obtaining the final result 9.
Hello!
First of all, let's find A. This is the opposite and hypotenuse we will be dealing with. Therefore, we will use the sin.
sin30= 0.5
This gives us the equation below.
a/12=0.5
a=6
Now we find b. This is the adjacent and hypotenuse. Therefore, we will use the cosine.
cos30≈0.87
This gives us the equation below.
b/12=0.87
b=10.44
I hope this helps!
To move a graph c units to the right, minus c from every x
minused 5 from every x
move f(x) to the right 2 units to get g(x)
I think probably not because everybody has a very different handspan and you probably wouldn't be able to get a very accurate average.
The answer to this question is B.37 cause its an isosceles triangle so two of the sides have to be congruent where the other side is not therefore the side of the missing angle is 37.
