We know by definition that complementary angles add up to 90 degrees. We can set up an equation using the ration given:

17x+13x=90, with x representing the amount you need to multiply the ratio by to get 90.

17x+13x=90
30x=90
x=3

We now know that the number we multiply the ratio by is 3. The smaller number in the ratio is 13, and so therefore we multiply it by 3.

3*13=39

The answer is 39 degrees.

32 is 40% of what number
anzhelika [568]
40% = 40 / 100 = 0.4

32 is 40% of what

= 32 / 40

= 32 / 0.4

= 80


-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-

U can also use this equation to solve it.

32 = 40%x

Simplfy

= 32 = 2/5x

Flib the equation.

2/5x = 32

Multipy both sides by 5/2

(5/2) * 2/5x = (5/2) * 32

x = 80.

anyanavicka [17]
U would measure it with the teaspoon and the 1/6 teaspoon
you would need 2 use the 1/2 teaspoon 4 times to get 2 teaspoons and the `1/6 teaspoon 4 times to get 2/3.

1/6+1/6=2/6*2=4/6 =2/3

hope this helps
