Question

Please help me with these

Answer 1

See explanation

Explanation:

I'm assuming that it wants you to describe how you found x. Alright.

For the second question, we see this is a 180 angle, and we subtract the existing 60 degrees to get 120 degrees. Divide this by the coefficient of x ( 3 ) and we get 40 or x.
For the third question, we see the top and bottom are equal and the lines are reflective so (5x-45) = 55. We use alteration to change this to 5x = 100 or x = 20.
For the fourth question, BAD is 110, and 110 - 55 = 55 = 5x, so x = 11 since 5x = 55 and (5)(11) = 55.

Answer 2

Answer: 37,40,20,11

Explanation:

From top to bottom:

x=90-53 or 37

x=(180-60)/3 or 40

5x-45=55 so 5x=100 so x=20

110=55+5x so 5x=55 so x=11
