First you have to put the 4 committees separate then put one by one in each group then you will see you answer in the groups
A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.
<h3>What is the rotation Transformation?</h3>
A rotation is a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise.
A square is a geometric figure which has all its four sides equal and all its interior angles are right angles (90°) .
Therefore, it can be rotated about its center by (360°).
It maps onto itself at 4 different angles of rotation (at every 90°).
Thus, we can reflect a square onto itself across 4 different lines of reflection (2 across the non-parallel sides and 2 across the vertices of the square).
Thus, we can conclude that A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.

Cross multiply
10/a = 15/30
10/a(a)(30) = 15/30(30)(a)
Simplify
1/a(a) = 1
15/30(30) = 15
10(30) = 15(a)
Simplify. Combine terms
300 = 15a
Isolate the a. Divide 15 from both sides
300/15 = 15a/15
a = 300/15
a = 20
A) a = 20 is your answer

18 and 35. The numbers whose sum 53 are 18 and 35.
The key to solve this problem is using a system of equations.
There are two numbers whose sum is 53. This number can be represented as x and y. So:
x + y = 53
Three times the smaller number is equal to 19 more than the larger. Let's set x as the smaller number and y the larger number. So:
3x = 19 + y
Clear y in both equations and let's use the equalization method to solve for x:
y = 53 - x and y = 3x - 19
Then,
53 - x = 3x - 19
53 + 19 = 3x + x ---------> 3x + x = 53 + 19 -------> 4x = 72
x = 72/4 = 18
To find y, let's substitute x = 18 in the equation x + y = 53
18 + y = 53 --------> y = 53 - 18
y = 35
