Answer:
subtracting 7 from 12
Step-by-step explanation:
That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives
Answer:
21

Good luck ..have a nice day
Answer:
x = 11
Step-by-step explanation:
In ΔSTU ,
m∠S = (11x+3)° ; m∠T = (2x+16)° ; m∠U = (x+7)°
According to angle sum property of a triangle , sum of all the interior angles of the triangle is 180°.
So,




Answer:
x = 52 degrees.
Step-by-step explanation:
Here we make use of the fact that the interior angles of any triangle add up to 180 degrees. Before this we must find an algebraic expression for interior angle RQS:
Since angle RQS + x + 72 = 180 degrees, angle RQS is equal to 180 -72 - x, or 108 - x.
The sum of the three interior angles is then
108 - x + 90 + 34, or 232 - x degrees, and this sum must equal 180 degrees.
Then 232 - x = 180. Solving for x, we get x = 52 degrees.
complementary angles = 90 degrees
two angles would be BGC (35 degrees) and CGD ( 55 degrees)
35+55 = 90
