Answer:
Triangular prism;
Triangular base, 9 edges, 5 faces (2 triangular and 3 rectangular) and 6 vertices
Answer:
The value of A is 1, D is 0, E is -2 and F is 0.
Step-by-step explanation:
The given equation is
...(1)
The standard form of the circle is
Where, (h,k) is the center of the circle and r is the radius.
It can be written as
....(2)
On comparing (1) and (2) we get.
Therefore the value of A is 1, D is 0, E is -2 and F is 0.
Knowing that all triangles angles add up to 180*:
24* + x + ? = 180*
Knowing the straight line is 180*:
180* - 122* = 58*
The equation then is:
24* + x + 58* = 180*
Then solve for X:
(82* + x) - 82* = (180*) - 82*
<u>x = 98* or C</u>
Answer:
Note :
The perimeter is : AB + BC + CA
AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180
AB = √(36×5) = 6√5 units
same method for : BC ; CA ..........
