Question

Find the value of x.

Answer 1

Answer:

x=50°

Step-by-step explanation:

<RPQ=90°, <PQR=40°, <PRQ=x°

<RPQ+<PQR+<PRQ=180°

90°+40°+<PRQ=180°

130°+<PRQ=180°

<PRQ=180°-130°

<PRQ=50°=x°

Answer 2

Answer:

In triangle PQR

PQR + QRP + RPQ = 180. ( angle sum property )

x + 40 + 90 = 180

x + 130 = 180

x = 50
