Solve for x.
the picture shows a triangle with A being x0 , B being 2x0 and C being a small square.
What is the correct answer?
A. 30
B. 45
C. 60
D. 90
To solve for x, we need to use the fact that the angles in a triangle add up to 180 degrees.
Since angle A is x0 and angle B is 2x0, we can set up an equation: x0 + 2x0 + angle C = 180
Combining like terms: 3x0 + angle C = 180
Since angle C is in a square, we know that all angles in a square are right angles, which means angle C is 90 degrees.
So now we have: 3x0 + 90 = 180
Subtracting 90 from both sides: 3x0 = 90
Dividing by 3 on both sides: x0 = 30
Therefore, the correct answer is A. 30.
