Find the measures of the interior angles of the triangle.
jeka94

Answer:

∠A = 30°

∠B = 60°

∠C= 90°

Step-by-step explanation:

This is a right triangle, you can see it mainly by the red square in C, and it is always used to mark 90 degrees.

Knowing that, you now know <em>∠C is 90°</em>

Now, to find ∠B, you should use the following equation:

  • A+B+C = 180°

This means that the sum of the three angles of a triangle gives 180. ALWAYS. So to find the missing angle, ∠B, do the following:

Fill the values of the equation with the angles you now know:

  • 30° + B + 90° = 180

Solve the equation, passing the 30° and 90° to the other side of the equal sing with Inverse Operation:

  • B = 180° - 30° - 90°

<em>B = 60</em>

<em>Hope it helps!!</em>
