The two angles are 13 degrees and 77 degrees respectively. Since they are complementary, they add together to make a total of 90 degrees.
In this question, we are seeking the measure of two angles. These angles are complementary, meaning together they add up to 90 degrees. Let's denote the first angle as 'x' and the second angle (which is 64 degrees more than the first) as 'x+64'.
Since they are complementary, this indicates that:
x + (x + 64) = 90
This simplifies into:
2x + 64 = 90
We can then subtract 64 from both sides, giving:
2x = 90 - 64, so 2x = 26
Therefore, if we divide both sides by 2 to isolate 'x', we get:
x = 13
So, the first angle measures 13 degrees. The second angle, as specified in the question, is 64 more than the first angle, so it measures:
x + 64 = 13 + 64 = 77 degrees
The first angle measures 13 degrees and the second angle measures 77 degrees.

The solution is 0.06 < 0.2 < 4
The inequality equation is 0.06 < 0.2 < 4 and is True
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
A = one sixth of thirty six hundredths is less than two tenths less than four
Substituting the values in the equation , we get
One sixth of thirty six hundredths = ( 1/6 ) ( 36/100 )
One sixth of thirty six hundredths = ( 6/100 ) = 0.06
And ,
Two tenths = ( 2/10 ) = 0.2
So , the inequality equation is
0.06 < 0.2 < 4
The equation satisfies the relation
Hence , the inequality equation is 0.06 < 0.2 < 4
