Question

4. In PQR, PQ = PR, P = x + 10° and Q = 4x -5°, then find each of the angles of PQR.​

Answer 1

Step-by-step explanation:

Since PQ=PR angle Q=angle R

• therefore P+Q+R=180
• (linear pair)
• Substitute the values
• (x+10)+(4x-5)+(4x-5)=180
• 9x=180
• x=180/9
• x=20
• angle P=30
• angle Q=75=angle R
