Does any one know the answer?

Solution:

Given expression is .

Rationalise the denominator means removing the root terms in the denominator.

To rationalise the denominator:

Multiply the numerator and denominator by the conjugate .

Use the algebraic identity in the denominator.

Hence the denominator is rationalised.

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
