<span>3x+3x+6x=180</span>

<span>12x=180</span>

<span>x=<span>18012</span>=15</span>

So, the measure of the angles are:

<span>3x=3×15=45</span>
<span>3x=3×15=45</span>
<span>6x=6×15=<span>90</span></span>

Select all of the values for a that would make the inequality 2x &gt; 10 true.
babunello [35]

Answer:

Step-by-step explanation:

2x > 10       Divide by 2

2x/2 >10/2

x > 5

x cannot be 5 or anything smaller.

In English, x >5 reads as x must be greater than 5. (It can't be equal to 5 because 5 is not greater than 5)

The only two items that work are

8 which is greater than 5 and

30 which is also greater than 5

A = 40° (Vertically opposite angles) 

b = 180 - 90 - 40 = 50° (Angles in a triangle add up to 180)

c = 180 - 65 = 115° (Adjacent angles on a straight line)
