Answer:
5 x + 1
Explanation:
5 × + 50°
Any non - zero expression raised to the power of 0 equals 1
x = 12
The sum of interior angles in a triangle is equal to 180°
since this is a right triangle
90° + 2x + 1 + 5x + 5 = 180° add like terms
7x + 96 = 180 subtract 96 from both sides
7x = 84 divide both sides by 7
