Answer:
33
Step-by-step explanation:
3 years ago, the difference in ages was twice Daniel's age. So, Daniel was 20/2 = 10 years old at that time. Ben was 30.
Now, Ben is 33.
_____
If two numbers have a ratio of 3:1, their difference is (3-1) = 2 times the smaller number.
3<em>x</em> + 120° + <em>x</em> + 120° = 360°
4<em>x</em> + 240° = 360°
4<em>x</em> = 120°
<em>x</em> = 30°
<em>y</em> = 1/2 (3<em>x</em> - <em>x</em>)
<em>y</em> = 1/2 (90° - 30°)
<em>y</em> = 1/2 × 60°
<em>y</em> = 30°
The answer is already given in your question. The inverse of a function
f is f-1, g is g-1, h is h-1 and i is i-1.
To explain why the inverse of
<span>f = {(1,2), (2,3), (3,4), (4,5), (5,6), (6,7)}
is
f-1 = </span><span>f -1 = {(2,1), (3,2), (4,3), (5,4), (6,5), (7,6)}
and that of the other functions to their corresponding inverses is because of the definition of the inverse of a function which is
f = (x, y)
f-1 = (y, x)
Simply, the x and y coordinates of a function are interchanged to get the inverse of the function.</span><span />

No it’s makes more than it so no
Answer:
70°
Step-by-step explanation:
90 + 20 + x = 180
110 + x = 180
x = 180 - 110
x = 70°
