There was a diagram but i dont need it to explain. <= angle

Complete the argument to show that m<SPQ= 2(m<RPQ). SO I need those 2 blanks filled in with the properties. Thank you sooo much!

m<RPQ= m<RPS Given

m<SPQ= m<RPQ + m<RPS ?____________

m<SPQ= m<RPQ+ m<RPQ ?____________

m<SPQ= 2(m<RPQ) Distributive property
