Answer 1

Answer:

Question 16

Steps for construction:-

1).Draw a line segment AB of 5cm.

2).Taking A and B as centre, draw arcs of 7cm and 6cm radius respectively.

3).Let these arcs intersect each other at point C.

Join AB and AC.

4).△ABC is the required triangle having length of sides as 5cm,7cm and 6cm respectively.

Question 17

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°
