Answer:
<h2>137.9°</h2>
Step-by-step explanation:
Supplementary angles add up to 180 °.
x + z = 180° → x = 180° - z
180° - 42.1° = 137.9°
Answer:
-2x - 6
Step-by-step explanation:
Multiplication must be done before addition or subtraction. Thus, we leave '4' as is and multiply out -2(x + 5), obtaining:
4 - 2x - 10, or -2x - 6
