<u>Answer</u>
2
<u>Explanation</u>
The two angles in the diagram are directly opposite. Directly opposite angle are equal.
∴ 12x - 7 = 4x + 9
put the like terms together,
12x - 4x = 9 + 7
8x = 16
x = 16/8
= 2
First set up the equation 12x-7=4x+9
Get all the x's on one side and number on one side so you have 8x= 16
You get X=2
Answer:
129.6º
Step-by-step explanation:
7 + 10 + 2 + 6 + 11 = 36%
QAV = 36% * 360º = 129.6º
20*15=300
It's "too short", but there's not much else to say here.
