Answer:
Step-by-step explanation:
We know that if two triangles are congruent , then the corresponding angles and sides are congruent by CPCTC.
Given:
Therefore , the corresponding angles and sides of are congruent.
∠F corresponds ∠H
∠M corresponds ∠Q
∠N corresponds ∠R
⇒ ∠F ≅ ∠H
∠M ≅ ∠Q
∠N ≅ ∠R
So , from the given options, the true congruency statements are :-
2.2+y=3

The number 128 is 20 percent of 640.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.
Let 128 is x percent of 640.
Here, x% of 640 =128
x/100 ×640 =128
6.4x=128
x=128/6.4
x=20%
Therefore, the number 128 is 20 percent of 640.

base= x+5
The height of the parallelogram is 4 miles and the base is 14 miles.
The area of a parallelogram is the product of the base and the height of the figure.
The area of a parallelogram = Base x Height
We have been given that the height is x-5, the base is x+5, and the area of the figure is 56 square miles.
So,
The area of a parallelogram = Base x Height
56=(x-5)(x+5)
Now Multiply x-5 and x+5
56=x²-25
Then Add 25 to both sides
81=x²
Now Take the square root of both sides
x=9
Now We can substitute it into the height and base thus,
Height: 9-5
Base=9+5
Therefore, the height of the parallelogram is 4 miles and the base is 14 miles.
