Solution
Solution Steps
Step 1: Identify the given angles and relationships in the first problem
In the first problem, we have a triangle with angles at points A, B, and C. The angle at C is given as 80°, the angle at A is given as \(2x - 10\)°, and the angle at B is given as \(x\)°.
Step 2: Use the triangle angle sum property
The sum of the angles in a triangle is always 180°. Therefore, we can write the equation:
\[ (2x - 10) + x + 80 = 180 \]
Step 3: Simplify the equation and solve for \(x\)
Combine like terms:
\[ 3x + 70 = 180 \]
Subtract 70 from both sides:
\[ 3x = 110 \]
Divide by 3:
\[ x = \frac{110}{3} \approx 36.67 \]
