The first both angles measure 45 degrees
Step by step explanation:
Complementary angles are angles that add up to 90 degrees and it said they both are equal which means both of them have to be half of the 90 degrees and half of 90 is 45 so 45 degrees

23. 1/2n-15
Answer:
Perimeter: 2(3x+6)+ 2(2x-4)
X=9
Step-by-step explanation:
In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:
Perimeter: 2(heights)+ 2(bases)
Perimeter: 2(3x+6)+ 2(2x-4)
IN order to solve for X we just have to insert the value of perimeter, which is 94:
Perimeter: 2(3x+6)+ 2(2x-4)
94=2(3x+6)+ 2(2x-4)
94= 6x+12+4x-8
94=10x+4
94-4=10x
x=90/10
x=9
So the value of x would be 9.
The answer is: " 9a² + 7a " .
