Question

Look at the two expressions.

3x−183⋅(x−6)

Are the two expressions equivalent? Use words and numbers to explain why or why not.

Answer 1

PQR +QRP+RPQ=180

105+ 40+ RPQ=180

145+ RPQ=180

RPQ= 180-145

RPQ= 35

LET DRAW A LINE PQ = 5CM

DRAW ANGLE P = 35°

DRAW ANGLE Q = 105°

FINALLY THEY INTERSECT EACH OTHER AT POINT R= 40°
