When you simplify the square root of a number, you are looking for factors of the number that are perfect squares that you can remove from under the radical. For example sq root of 8... it's not a perfect square but factors of 8 include 2 x 4... 4 is a perfect square so we can take it out of the radical by taking it's square root. Now you are left with 2* sq root of 2.

For sq root of 48

48 = 12 x 4

12 = 3x4 so we can say 48 = 3x4x4

so... sq root 48 = sq root 3x4x4

we have two 4's under the radical. Sq root x^2 = x so sq root 4^2 is 4

Pull it out from the radical and we are left with 4 * sq root 3

Can someone please help me with this question

lakkis [162]

A. Angle 3 is a vertical angle to angle 2 which means they are the same.

Angle 3 = 76 degrees

B. Angle 6 is also the same as angle 2.

Angle 6 = 76 degrees

C. Angle 8 + angle 6 form a straight line which equals 180 degrees

Angle 8 = 180 - 76 = 104 degrees
