Your answer would be x = 12
The triangle sum theorem states that the 3 angles in a triangle equal 180.
Since we have a 90 degree angle shown, we can add it to the other two and set it equal to 180.
30+90+6x-12=180
108+6x=180
6x=72
x=12

Answer:
u = -3
Step-by-step explanation:
Step 1: Write equation
-4 + 2u = -10
Step 2: Solve for <em>u</em>
<u>Add 4 to both sides:</u> 2u = -6
<u>Divide both sides by 2:</u> u = -3
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 + 2(-3) = -10
-4 - 6 = -10
-10 = -10
