Question

1. what is the angle degree of each angle in an equilateral triangle? 90 degrees 60 degrees 45 degrees 30 degrees

Explanation:

Step1: Recall triangle angle sum

The sum of angles in any triangle is $180^\circ$.

Step2: Analyze equilateral triangle

An equilateral triangle has 3 equal angles. Let each angle be $x$. Then $3x = 180^\circ$.

Step3: Solve for x

Divide both sides by 3: $x=\frac{180^\circ}{3}=60^\circ$.

Answer:

B. 60 degrees (assuming the option with 60 degrees is labeled as B, but based on the options, the correct one is "60 degrees" among the choices, so the answer is the option with "60 degrees")
