Answer:
9 ; 81
Step-by-step explanation:
one angle = x
It's complementary angle = 9*x = 9x
Sum of complementary angles = 90
x + 9x = 90
10x = 90
x = 90/10
x = 9
It's complementary angle = 9x = 9*9 = 81
9, 81
Complementary angles add to 90
Let x = first angle
The other angle is 9x
x+9x = 90
Divide each side by 10
10x/10 =90/10
The first angle is 9
The second angle is 9*9 =81
How to determine if the sum of several numbers, such as 13 + 45 + 24 + 17, is even or even without calculating anything. This is it in English if it helps.
