Which equation results from isolating a radical term and squaring both sides of the equation for the equation

D.

Step-by-step explanation:

We have been given a radical equation . We are asked to find the equation that results from isolating a radical term and squaring both sides of the equation for the equation.

Add on both sides:

Square both sides:

Using radical rule , we will get:

Using perfect square formula , we will get:

Therefore, option D is the correct choice.

c

step-by-step explanation:

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 .
