1/2(x + 4) = -12
1/2x + 2 = -12
1/2x = -10
x = -20
1. (c) 125/12
2. (a) 16
hope it helps
An acute angle is one that measures LESS than 90˚
An obtuse angle is one that measures between 90˚ and 180˚
A reflex angle is an angle that measures between 180˚ and 360˚
There are other many types of angles such as alternate angles and corresponding angles, but those 3 are the main ones.
Have a great day <3
