Kites have at least one pair of congruent opposite angles. Plsss helpp
Answer:
I mean you could have looked it up but, here is the answer...
Step-by-step explanation:
If a quadrilateral is a kite, then its diagonals are perpendicular. If a quadrilateral is a kite, then exactly one pair of opposite angles are congruent. If a quadrilateral is a kite, then one of the diagonals bisects the pair of non-congruent angles.
Kites or kite shapes have at least one pair of congruent opposite angles, and the provided statement is correct.
What are the properties of Kite shapes?
A kite is a closed shape quadrilateral which have 4 sides. In this 4 sides, the two pair of adjacent sides are equal.
Properties of kite shapes are listed below-
Two pairs of adjacent sides are equal in a kite shape.The kite has a pair of opposite angles which are equal.The long diagonal bisect the short one.Both the diagonals of the kite is perpendicular to each other.As, the kites has a pair of opposite angles which are equal.
Thus, Kites or kite shapes have at least one pair of congruent opposite angles, and the provided statement is correct.

The area, A, of a triangle is one-half the product of the triangle's base and height. A = A = (12)(5) A = ( b+ h) A = A = (b·h)
Answer:
A = (1/2) * b * h
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.
The area of a triangle is half the product of the base of the triangle and the triangle height. The area is given by the formula:
A = (1/2) * b * h
A = (1/2)bh = 0.5bh
Where A is the area of the triangle, b is the bae of the triangle and h is the height of the triangle.

Step-by-step explanation:
Using the substitution method, Vito is solving the following system of equations algebraically:
y + 3x =-4
2x – 3y =-21
Which equivalent equation could Vito use?
A) 2(-3x - 4) + 3x =- 21
B) 2(3x - 4) + 3x =- 21
C) 2x - 3(-3x – 4) =- 21
D) 2x - 3(3x - 4) =- 21
Answer:
The correct answer is Option C: [tex]2x-3(-3x-4)=-21[/tex]
Step-by-step explanation:
The given equations are:
[tex]y + 3x =-4\ \ \ Eqn\ 1\\2x-3y =-21\ \ \ Eqn\ 2[/tex]
The equations have to be solved using substitution method. In substitution method we find the value of a variable from one equation and put it in the other equation.
To find the value, we usually choose the equation in which a variable without any coefficient is available.
From equation 1
[tex]y +3x = -4\\y = -3x-4\\[/tex]
This value of y will be put in equation 2
[tex]2x-3(-3x-4)=-21[/tex]
It is the C option in choices
Hence,
The correct answer is Option C: [tex]2x-3(-3x-4)=-21[/tex]

How old will the father be when he will be twice as old as his son?
Answer:
40 years old
16 years old
Step-by-step explanation:
Son = 8 years old
his father is five times as old.
Father = 5 × 8
= 40 years
How old will the father be when he will be twice as old as his son?
Father = 2 × 8
= 16 years
Father:
Five times as old as son = 40 years old
Twice as old as his son = 16 years old
