The measure of two complementary angles are in the ratio 1 : 4. What are the degree measures of the two angles?

1 answer:

6 0

Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18

So the first angle is 18° and the second is 72° (18*4)

Hope this helps

What is 2. 3/6 +1/6 +1 2/3

Kaylis [27]

3/6+1/6+1 2/3
Make 1 2/3 into an improper fraction:
5/3
Give them all common denominators by multiplying both sides of 5/3 by 2:
10/6
Then the question becomes:
3/6+1/6+10/6
Now you add the numerators and the denominator stays the same:
14/6
Now you can simplify by dividing both sides by 2:
7/3
Now you can make it a mixed number:
2 1/3

Hope this helps :)
