Complementary means that the two angles sum to 90 degrees.
So based on the problem, let:
1st angle=5x+6
2nd angle=x
Now create an equation.
x+5x+6=90
6x=84
x=14
5x+6=76
answer: 14 degrees and 76 degrees

Answer:
18u most likely
Step-by-step explanation:
the triangle is 6 units wide and half of it (the height) is 6. so 6 x 6 = 36 divided by 2 = 18u

Equivalent expressions are expressions that have the same values.
The expression is and the number is 12
Represent the number with x.
So, the sum of a number (x) and 7 would be represented as: x + 7
Three times the sum would be represented as: 3(x + 7)
This expression is equivalent to 57.
So, we have:
Divide both sides of the equation by 57
Subtract 7 from both sides of the equation
Hence, the number is 12
