0.55 can be converted to:
55/100
= 11/20
It is terminating it is 45/100
maybe xd ad something else please
One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
Answer:
the number (x) is 120.
Explanation:
<em>100% + 60% = 160% = 1.6 </em>
<em />
<em>(just multiply it by 1.6 because it is equal to 60%)</em>
