You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.
To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.
So 1.38 radian * 180° / 3,1416 = 79 °.
So the angle in the Column A is 2° wider than the angle in the Column B.
Answer:

Step-by-step explanation:
we have

To find out f(x+h), substitute the variable x by the variable (x+h) in the function f(x)
so


The first one is 2x-3y/2
The second one is 1/x+2
The third one is (2x-5y)/(2x+5y)
The fourth one is x^2/z^2
Answer:
189sq.cm
Step-by-step explanation:
Area of a parallelogram = b×h
= 21× 9
= 189 cm^2
