Step-by-step explanation:
constant variation is direct and the slope is constant
Answer:
rational
Step-by-step explanation:
a rational number is a number that can be expressed as the ratio of two numbers. 33 to 3 is a ratio, so this works.
it is not a whole number because it is not a counting number
it is also not a natural number because it is not a whole number
The value of a and b are; 4.8 and 10.8 respectively.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We have been given a figure which shows that;
Let x, y z, and u lines are parallel.
Therefore, by using proportion we can say that
a/ 12 = 4/ 10
thus, a = 4/ 10 (12)
a =2(12)/ 5
a = 24/5
a = 4.8
Now, 12/b = 10/8
b = 12 (8/10)
b = 6(8)/ 5
b 54/5
b = 10.8
Hence, tha value of a and b are; 4.8 and 10.8 respectively.

We are asked to find the positive angle that is co-terminal to 132°.
We know that co-terminal angles are angles who share the same initial side and terminal sides.
To find the positive angle that is co-terminal to 132°, we will add 360 degrees to 132°.
Therefore, the positive angle that is co-terminal to 132 degrees is 492 degree and option A is the correct choice.
