Question

8. Verify p- (-4) = p + q in the following (2) p = f g = -2 (c) p = -243, 4 = -540 (b) p = 3, 9 = 11 (d) p = -2005, q = -400
​

Answer 1

Answer:

In △PQR

∠P+∠Q+∠R=180

∠P+40+50=180

∠P=90

Now, in △s, ABC and PQR,

BC=QR ...(Given)

∠A=∠P=90°

∠C=∠R=40° ...(Given)

Thus, △ABC≅△PQR (ASA postulate)

The given statement is true.
