1.given: triangle pqr with m∠p=(2x)° , m∠q=(4x)° , and m∠r=(6x)° . prove: x = 15 by the triangle sum theorem, the sum of the angles in a triangle is equal to 180°. therefore, m∠p+m∠q+m∠r=180° . using the (2x)°+(4x)°+(6x)°=180° . simplifying the equation gets 12x = 180. finally, using the division property of equality, answer to each box to complete substitution property, distributive property, angle addition postulate, x=12 x=15 x=30
