The diagram shows statements to prove that both triangles are congruent.
Hence;



Step 1 showed two sides that are congruent for both triangles
Step 2 showed two angles that are congruent
Step 3 showed two sides that are congruent
Therefore, the triangles are congruent by the side-angle-side theorem
The circumference of the circle is 53.41.
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
Answer:
Width = 17
Length = 92
Step-by-step explanation:
Perimeter of rectangle = 2 (length + width)
let us take width be x
length = 7 + 5x
width = x
so let us put these value
2 (length + width) = 218
2 (7 + 5x + x ) = 218
2 (7 + 6x ) = 218
14 + 12x = 218
12x = 218 -14
12x = 204
x = 204/12
x = 17
Width = x
= 17
Length = 7 + 5x
= 7 + 5(17)
= 7 + 85
= 92
