Step-by-step explanation:
The sum of the three angles in a triangle must be . Since this triangle has a right angle, we know that it is °, so the sum of the remaining two angles must be .
We can set up an equation for the two remaining angles to determine the value of :
The slope is 1 because there is one x
40 tens is basically 40 times 10 so 400
which is 4 hundreds
C - a rational number is one that can be expressed as a fraction and does not continue indefinitely; all integers are rational numbers as we can see that 5 can be expressed as 5/1 and 1/4 is also a fraction and thus rational. The product of two fractions will be a fraction and is thus also rational
Examples of irrational numbers can be the value π or e
